Best Window Shutters When Your Openings Are Odd Sizes
Five shutter listings, two exterior categories, one interior maker, and a size chart that runs from 31 inches to 63 inches tall. Here's which pair fits which opening, and what a mis-measure by half an inch actually costs you.
The best window shutters here are the Ekena Millwork Lifetime Vinyl LL1S14X03600BL pair, because a 14.5-in. W x 36-in. H louvered pair with a limited lifetime warranty covers the most common exterior opening in this set. If your opening runs 63 inches tall instead, the Polaris Homeside raised panel at 14.5 x 63 in is the one that fits. Get the size wrong and the shutter either floats above the sill or crowds the trim, and no amount of quality vinyl fixes a pair that's two inches short. That's the failure mode nobody warns you about.

How the five picks map to five different buyers
Nobody buys shutters in the abstract. You buy them because one specific window looks wrong, and the fix has to fit that window. So I sorted these five by the buyer standing in front of the opening, not by a score.
- The exterior homeowner with a 36-inch window. Two picks land here, both from Ekena Millwork, differing only in width: 14.5 inches or 12 inches. Same 36-inch height, same limited lifetime warranty, same open louver style with a cathedral top center mullion.
- The homeowner with a tall, narrow opening. The Polaris Homeside raised panel measures 14.5 x 63 in. That's a very different silhouette, suited to a full-height window or a flanking sidelight.
- The interior buyer who wants a classic look. The SUNCRAFT traditional front tilt rod model at 20"W x 31"H is the recognisable plantation shutter shape, tilt rod down the middle of the panel.
- The interior buyer who hates the tilt rod. Suncraft's second listing is the same 20"W x 31"H footprint with the rod removed and, per the listing, a hidden gear instead.
- The person who hasn't measured yet. You're not in this list. Go measure first. Everything below assumes you have numbers.
Two of the five are exterior louver shutters, one is an exterior panel shutter, and two are interior plantation shutters. That's three different products wearing one keyword, which is exactly why size and location decide this more than brand does.
Why measuring beats material in best window shutters
Every listing here talks about material. Vinyl that never needs painting, poly resin that resists cracking, color-through technology that hides scratches. All of it matters over ten years. None of it matters if the panel doesn't fit.
Here's the trick with the best window shutters: the number that decides your purchase is the height, and the number that ruins it is the tolerance. Ekena Millwork states plainly that "widths and lengths are nominal +/- 1/2 inch" due to the materials. Half an inch either way. On a 36-inch opening with tight brick trim, that half inch is the difference between a clean reveal and a shutter you have to trim on site.
The spread across these five is wide:
- 31 inches tall on both Suncraft interior panels
- 36 inches tall on both Ekena Millwork louver pairs
- 63 inches tall on the Polaris Homeside panel
Widths run 12 inches, 14.5 inches and 20 inches. There is no overlap in the middle. You either match one of those numbers closely or you're buying the wrong pick.
Most shoppers miss the second half of this: count. The two Ekena listings ship a count of 2, a matched pair per order. The Polaris, both Suncraft listings and every interior option here show a count of 1. Flanking a single window means two orders on three of these five. Work that out before you compare anything else.
1. Ekena Millwork Lifetime Vinyl LL1S14X03600BL — Best overall
A matched pair at 14.5-in. W x 36-in. H with a limited lifetime warranty, and the shutter buyers here choose most often.

Best for: standard 36-inch exterior openings needing a matched pair Skip it if: your opening is taller than 36 inches
Within this set, this pick wins on three things at once. It's the cheapest of the five, it ships two shutters per order, and it carries a limited lifetime warranty that only the Suncraft traditional model comes close to matching. It also sells faster than anything else here, and it's the only listing with more than one seller stocking it: two sellers, versus one for the other four.
The specification that earns it the top slot is width. At 14.5 inches wide and 36 inches tall, with a stated depth of 1 inch, it lands on the most common exterior window flank size in the set. The style is a standard cathedral top center mullion with open louvers, so the top rail curves rather than running flat. Colour is listed as 002 - Black.
Ekena says the pair installs in minutes using the included Shutter-Lok fasteners and matching screws, and that the hardware is colour-matched. That's the manufacturer's claim, not a measured install time, but the hardware being in the box is a real advantage over listings that don't mention fasteners at all.
The trade-off: at 4.26 lb for the pair, it's light, and light vinyl louvers are decorative rather than functional. These don't close over the glass. If you want operable storm protection, no pick in this set delivers it.
Pros:
- Cheapest of the five picks here
- Ships a count of 2, a matched pair
- Limited lifetime warranty stated on the listing
- Installation hardware and matching screws included
- Two sellers stock it, unlike the other four
Cons:
- Fixed at 36 inches tall, no taller option in this listing
- Nominal sizing tolerance of plus or minus half an inch
- Decorative louvers, not operable or closable
- Black only on this model number
2. Polaris Homeside Raised Panel Vinyl Shutters — Best for small spaces
The only 63-inch-tall option here, and the only raised panel style, which makes it the pick for tall narrow openings and sidelights.

Best for: tall narrow openings on a 63-inch run Skip it if: you need two panels from one order
This is the outlier, and that's the point. At 14.5 x 63 in with a listed depth of 1 inch, it's nearly twice the height of anything else in the set. Tall narrow windows, sidelights beside a front door, and stairwell openings all need that proportion, and no other pick covers it.
It's also the only raised panel design here. The other exterior picks use open louvers. Polaris describes deep inset panels with clear lines, which reads flatter and more formal from the street than a louvered slat pattern does. If your house has panelled doors or shaker trim, the geometry matches better.
Polaris lists a colour-through process that resists fading and hides scratches, plus maintenance-free construction requiring no painting or staining, and mounting on almost any surface with included hardware options. Those are the manufacturer's claims. The listing also mentions multiple colour choices, though this specific model is Black.
Where it loses: the count is 1, so flanking one window takes two orders, and there's no published warranty on the listing at all. That's a real gap against both Ekena picks, which state a limited lifetime warranty. It also sits roughly mid-range for this set on price while giving you half as many panels as the cheaper Ekena pair.
Pros:
- Only 63-inch-tall option in the set
- Only raised panel style here, not louvered
- Colour-through construction claimed to hide scratches
- Second-fastest seller of the five
Cons:
- Count of 1, so a pair means two orders
- No warranty stated on the listing
- Single listed colour on this model
- Costs more per panel than either Ekena pair
3. Ekena Millwork Lifetime Vinyl LL1S12X03600BL — Best for beginners
The narrow 12-inch version of the winner, same 36-inch height and same lifetime warranty, for reveals too tight for a 14.5-inch panel.

Best for: narrow 12-inch reveals and first-time installers Skip it if: your opening is wider than 12 inches
This is the same product family as the winner with 2.5 inches shaved off the width. Everything else holds: 36-inch height, 1-inch depth, open louvers, standard cathedral top center mullion, colour 002 - Black, limited lifetime warranty, Shutter-Lok fasteners and matching screws in the box.
Why it's the beginner's pick rather than a downgrade: at 3.53 lb per pair, it's the lightest thing here, and a 12-inch-wide panel is easy to hold flat against siding with one hand while you drive the first fastener. Wider panels flex more and want a second person. If this is your first shutter install and you've got the wall space, the narrower panel is genuinely more forgiving.
It's the second-cheapest of the five, and it ships a count of 2, so one order finishes one window. That combination is rare in this set.
The catch is that 12 inches is narrow. On a wide picture window it reads as an afterthought, a strip of trim rather than a shutter. Proportion matters more than most people expect, and this one only works when the opening is genuinely narrow. It also moves far slower than the 14.5-inch version and only one seller lists it, which suggests fewer buyers find their window in this size.
Pros:
- Lightest pair in the set at 3.53 lb
- Ships a count of 2 for one window
- Limited lifetime warranty stated
- Second-cheapest pick here
- Hardware and matching screws included
Cons:
- 12-inch width looks undersized on wide windows
- Only one seller lists it
- Same plus or minus half-inch size tolerance
- Fixed 36-inch height only
4. SUNCRAFT SHUTTERS Plantation Shutters — Runner-up
The interior pick with a traditional front tilt rod and a claimed 25-year warranty, custom made to your measurements.

Best for: interior rooms wanting a traditional tilt rod Skip it if: you want an exterior-facing shutter
This is the only pick here that's built to your numbers rather than sold in a fixed size. The listing shows 20"W x 31"H in White, and Suncraft states the panels are custom made in 10 days to fit your windows. That changes the whole calculation, because the size tolerance problem that hangs over the vinyl exterior picks doesn't apply the same way.
The construction claim is durable poly that won't fade or crack and never needs painting, with a 25-year warranty and a traditional front tilt rod. Suncraft also says the panels are made in North America and designed for DIY installation. Those are listing claims, not verified figures, but a stated 25-year term is the second-longest warranty language in this set behind Ekena's limited lifetime.
The front tilt rod is the deciding feature against the premium Suncraft pick below. A visible rod down the panel face means you grab it and tilt all the louvers together. It's the mechanism most people already know how to use, and there's nothing hidden to fail.
Where it falls short: it's in the most expensive tier of this set, the count is 1 per order, and it's the slowest-selling of the two Suncraft listings' close pair. Only one seller stocks it. It also publishes no weight, no depth and no material specification beyond "poly," which is thinner documentation than either Ekena listing offers.
Pros:
- Custom made to your window measurements
- Traditional front tilt rod, familiar to operate
- 25-year warranty claimed on the listing
- White finish that Suncraft says never needs painting
Cons:
- Premium price tier, count of 1 per order
- No published weight, depth or slat width
- Only one seller lists it
- Interior only, no exterior application
5. Suncraft Shutters, no front tilt rod — Best premium
Same 20"W x 31"H custom interior panel with the tilt rod removed and a hidden gear in its place, for a cleaner face.

Best for: interior windows where a visible tilt rod bothers you Skip it if: you're covering more than one window on a budget
The design difference is the entire reason this exists. Suncraft describes a unique layout with no front tilt rod and a hidden gear, which leaves the louver face uninterrupted. Look at a plantation shutter with a rod and one without, side by side, and the rodless version reads as newer and less busy. That's the whole pitch.
Specification-wise it mirrors the runner-up: 20"W x 31"H, White, count of 1, model ODP-89. Suncraft claims high-grade poly resin resistant to cracks, damage and warping, custom manufacture to your measurements, and DIY installation. Same category of claim as the traditional model, minus the stated warranty term.
I'd point interior buyers here when the shutters sit in a sightline you look at every day: a kitchen window over the sink, a bathroom, a bedroom facing the bed. Those are the places a rod becomes visually loud.
The honest losses stack up though. It's the most expensive pick here, the slowest seller of the five by a wide margin, and unlike the traditional Suncraft model it publishes no warranty term at all. The hidden gear is also a mechanism you can't see or service, and there's no listed information about what happens if it stops turning freely. For the highest price in this set you get a cleaner face and less published documentation than the pick directly above it.
Pros:
- No front tilt rod, hidden gear mechanism
- Custom made to your window measurements
- Poly resin claimed resistant to warping and cracks
- Cleanest panel face of the two interior picks
Cons:
- Most expensive pick in this set
- No warranty term stated on the listing
- Slowest seller of the five
- Hidden mechanism you can't inspect or adjust
- Count of 1, so multi-window rooms need multiple orders
Interior or exterior: which best window shutters do you actually need?
Search results for the best window shutters mix two unrelated products, and buying the wrong one is the most expensive mistake in this category. Here's the split in this set.
Exterior, three picks. Both Ekena Millwork louver pairs and the Polaris Homeside raised panel are exterior shutters. They mount on the wall beside the window, they're decorative, and they don't close. All three are Black. All three use vinyl. Two of the three sit in the exterior louver shutter category; the Polaris sits in exterior panel shutters.
Interior, two picks. Both Suncraft listings are interior plantation shutters. They mount inside the window frame, the louvers tilt, and they control light and privacy in a room. Both are White. Both are custom made.
Quick way to tell which you need: if you're trying to fix how your house looks from the street, buy exterior. If you're trying to fix how a room feels from the inside, buy interior. If someone's told you shutters will block afternoon glare, that's interior, and only two picks here do it.
One caveat on the interior pair: neither Suncraft listing publishes a slat width, a frame depth, or a mounting depth requirement. Interior shutters need clearance inside the window recess, and that number isn't stated. Measure your recess depth before you order.
What does a longer warranty really cover?
Three of the five picks state warranty terms, and two state nothing. That gap is worth reading carefully.
- Limited Lifetime Warranty: both Ekena Millwork vinyl pairs
- 25 Year Warranty: the SUNCRAFT traditional front tilt rod model, as a listing claim
- Nothing published: the Polaris Homeside panel and the rodless Suncraft
The word doing the work in Ekena's term is "limited." A limited lifetime warranty on vinyl typically covers the material rather than the outcome, and the listing doesn't spell out what's included. I read it as coverage against the vinyl failing, not against a colour shift over fifteen summers or a fastener pulling out of siding.
Suncraft's 25-year term appears as a bullet on the listing, so treat it as the manufacturer's stated claim. It's a definite number, which is more than the other two silent listings give you.
Where the silence matters most is the Polaris. It's the mid-priced exterior pick and the only one at 63 inches, so a buyer with a tall window has no alternative in this set. Going in with no published term means the fade-resistance claim is the only durability assurance on offer, and a claim isn't a warranty.
How do you install a pair without a helper?
Both Ekena picks list installation hardware in the box: Shutter-Lok fasteners plus matching screws, colour-matched to the shutter. Polaris mentions included hardware options for mounting on almost any surface. Both Suncraft listings describe DIY installation but don't itemise what ships.
In practice, the order that works on a light vinyl exterior panel:
- Hold the panel against the wall and mark the top fastener hole only.
- Drill that one hole, set the top fastener, and let the panel hang.
- Step back and check the panel against the window head and the sill line.
- Adjust while only one fastener is in, then mark and drill the rest.
That sequence is why the 12-inch Ekena at 3.53 lb is the easier first install than the 14.5-inch at 4.26 lb. Less width means less flex and less weight fighting you at step two.
Two things to sort before you drill. First, siding type. Vinyl siding, brick and fibre cement each want different fasteners, and "almost any surface" in a bullet doesn't mean the right screw is in your box. Second, the half-inch tolerance Ekena publishes. Dry-fit both panels before committing to holes, because a pair that's each a half inch narrow reads visibly off-centre once mounted.
The verdict
The Ekena Millwork LL1S14X03600BL is the default pick among the best window shutters in this set, and the reasoning is straightforward. It's the cheapest of the five, it ships a matched pair of 2 at 14.5-in. W x 36-in. H, it carries a limited lifetime warranty, it includes its own Shutter-Lok fasteners and matching screws, and it's the shutter buyers here choose most often. Nothing else in this group combines a stated warranty, a pair per order and the lowest price.
Two conditions flip that recommendation, and both are about the window rather than the product.
If your opening runs taller than 36 inches, the Ekena is simply the wrong size and no discussion of vinyl quality changes it. Go to the Polaris Homeside raised panel at 14.5 x 63 in, accept that the count is 1 and you'll need two orders, and accept that no warranty term is published.
If you're working inside rather than outside, both Ekena picks are irrelevant. The SUNCRAFT traditional front tilt rod model is the interior runner-up, and its exact advantage over the Ekena is that it's custom made to your measurements in a stated 10 days, with a 25-year warranty claim, rather than sold in a fixed size with a plus or minus half-inch tolerance. Choose the rodless ODP-89 over it only when the panel face is something you'll be looking at daily.
FAQ
Are cheap window shutters worth buying?
Cheap window shutters are worth buying when the cheap option carries the same documentation as the expensive one. The Ekena Millwork 14.5-in. W x 36-in. H pair is the least expensive pick here and still states a limited lifetime warranty and includes hardware, while the most expensive pick in this set publishes no warranty term at all. Price position and durability documentation don't track together in this category.
Is it worth paying more for custom-made shutters?
Worth paying more for custom manufacture depends on whether fixed sizes fit your window. Both Suncraft interior picks are made to your measurements, which removes the plus or minus half-inch tolerance that Ekena publishes on its vinyl pairs. If your opening is a standard 36 inches tall, the fixed-size option saves money. If it's an unusual size, custom is the only route in this set.
What size window shutters do I need for a 36-inch window?
For a 36-inch window, both Ekena Millwork picks are built at 36 inches tall: one at 14.5 inches wide, one at 12 inches wide. Choose the width by how much wall you have beside the opening. Ekena states widths and lengths are nominal, plus or minus half an inch, so dry-fit before drilling. Neither shutter closes over the glass.
Ekena Millwork or Polaris Homeside: which should I choose?
Ekena Millwork or Polaris comes down to height and count. Ekena gives you 36 inches, a pair of 2 per order, a limited lifetime warranty and the lowest price here. Polaris gives you 63 inches, a raised panel instead of louvers, a count of 1 and no published warranty. Tall window means Polaris. Standard window means Ekena, comfortably.
What mistake do first-time shutter buyers make?
The mistake first-time shutter buyers make is assuming one order equals one window. Only the two Ekena Millwork listings ship a count of 2. The Polaris panel and both Suncraft interior shutters show a count of 1, so flanking a single window takes two orders. Check the count field before you compare prices, or your budget doubles at checkout.
Start with a tape measure, not a shopping cart. Write down your opening height, your opening width, the wall space either side, and whether you're fixing the view from the street or the light in the room. Those four numbers eliminate three of these five picks in about a minute. For most people the answer lands on the Ekena Millwork 14.5 x 36-inch pair, and the reason is less about vinyl than about arithmetic: it's the only pick here that finishes one window, in one order, at the lowest price, with a warranty term actually printed on the listing.
