How to Measure Bench Cushions for Custom Entryways and Patios

Custom bench cushions are made to your exact measurements. How to measure bench cushions is the same conversation on every call — built around the geometry of your specific seat instead of forced into an off-the-shelf rectangle. This guide covers sizing. It covers fabric and foam, and the small details that decide whether the finished cushion fits as it belongs.

Sarah measured her mudroom bench with a tailor's tape twice and still cut the paper template a half-inch short on the back edge. Two cushions arrived, both lovely, both wrong by an inch. She emailed a photo, our team rebuilt the template from the photo's diagonal, and the second pair fit like the bench had been built around them.

What follows is the same checklist our customer-care team runs through on a real call — what to measure, what fabric to choose, and what to skip — without padding or sales pressure.

Key takeaways

• Custom bench cushions are worth ordering custom — standard sizes rarely match real furniture within the half-inch.
• Sunbrella performance fabric is the engineering story behind why custom cushions hold color and shape through real seasons.
• Three numbers do most of the work — length, width, thickness. Templates handle everything that isn't a clean rectangle.
• Pick foam by use case: dry-fast for outdoor, high-density 1.8–2.0 lb for indoor seating, fiberfill for backs.

Getting Your Bench Measurements Right

Start with the basics — length, width, and thickness — and write each number down. Do it before anything else. For custom bench cushions, the order matters. Measure. Write. Order: measure twice on the actual seat or bench, not on the cushion you already own, because old cushions compress with use and read short by an inch or two.

Use a metal tape (a soft fabric tape stretches and reads long), and pull it tight along the surface — not floating over it. For curved or angled seats, lay a sheet of butcher paper or kraft paper over the seat, trace the outline, and send the template along with your order. The template removes the guesswork the second a complex shape enters the picture.

Common mistake one: measuring with old cushions in place. Old foam compresses. The seat reads short by an inch or two. Common mistake two: rounding down. Round up to the nearest quarter-inch. Fabric and foam compress slightly during finishing. A hair of extra room reads as a perfect fit — not a loose one.

Once the numbers are in, check them against a second method. If you measured with a tape, run a string across the same span and lay it flat — the string should read identically to the tape. If there's any disagreement, the seat probably isn't a clean rectangle, and a paper template is the cleanest way to capture what's actually there. That extra ten minutes is the difference between a cushion that fits and one that's almost right.

On the order page itself, enter the dimensions in the same order you measured them — length first, then width, then thickness. Customer care reviews every custom order before it goes to cut. If your numbers look unusual, they'll reach out. Email or chat, before the fabric is touched.

That review step has caught hundreds of orders where the customer measured width as length or forgot to add an inch for the cushion overhang.

Measuring the Length and Width

For measuring the length and width, the practical move is straightforward: write your numbers down before you order, choose the spec that matches how the piece actually gets used, and lean on the customer-care team if anything reads as borderline. Most fit questions are solved on the phone before the fabric is cut — that's the point of the custom-fit promise.

Choosing the Perfect Cushion Thickness

This part of the guide focuses on choosing the perfect cushion thickness. The short version: every detail in this section affects how the finished cushion or cover performs once it's installed, so it's worth the few extra minutes to read through before you order.

For sizing your bench cushion, the practical advice is straightforward — work in inches, write each number twice, and keep a paper template handy for anything that isn't a clean rectangle. That habit alone solves the majority of fit problems before they happen.

Ties and Non-Slip Backing Options

Cushion-securing options break down into three: ties (sewn into the back edge, wrap around the chair stretcher), and non-slip backing (a rubberized weave on the underside that grips the seat). Pick by use case — ties for chairs the wind catches, and non-slip for indoor benches, the kids slide off.

On L-shape benches and window seats, ties at the back-corner intersection keep the cushion from migrating during cleaning. On chaises and loungers, two ties at the head end and one at the foot end are usually enough — more than that, and the cushion gets harder to flip for even wear.

Once your numbers are written down and the fabric is chosen, the order itself is the easy part. Head to the matching product page on zipcushions.com, enter the measurements, pick fabric and foam, and the team handles the cut.

Customize Your Cushion when you're ready. If anything about the measurements feels off, customer care will walk you through it before the fabric is cut — the perfect-fit means we'd rather catch it on the phone than ship the wrong piece.

Care & Cleaning — Keeping Your Order Looking New

Sunbrella, Agora, and all other fabric covers are zippered by default with YKK industry-grade zippers — that's the design choice that makes long-term care actually doable. Pull the cover off the foam, run it through a gentle wash on cold, and air-dry it flat. Hot water and tumble drying shrink the weave; cold and line-dry keep the fit identical to day one.

For everyday spot cleaning, mild dish soap on a soft brush handles most stains — coffee, juice, sunscreen, the usual outdoor culprits. Avoid bleach on patterned fabrics — even though Sunbrella is bleach-safe, the pattern dye lives at the fiber level, and aggressive cleaners can read slightly lighter over time.

Off-season storage is the other half of the equation. If your patio sees a real winter, bring the cushions inside or store them in a breathable bag (a cotton tote, a mesh storage bag) — never sealed plastic, which traps moisture and invites mildew. If you leave them out year-round, pair them with a ZIPCovers protective cover sized to your furniture; that combination is the longest-term play for keeping cushions that still look new in year ten.

What to Expect from a ZIPCushions Order

Every order starts with the measurements you submit. Once the order is in, customer care reviews the dimensions against the shape type, including trapezoid, rectangle, chaise, daybed, and flags anything that looks off before the fabric is touched. That review step usually catches the same handful of issues: dimensions in the wrong slot, a missing thickness, and an asymmetrical shape ordered as a clean rectangle.

Fabric is cut to your numbers, sewn at the seam pattern the cushion shape calls for, and the foam is cut a hair larger than the cover so the finished cushion sits firm rather than loose. Sunbrella covers are zippered by default, so you can remove them for cleaning — most owners spot-clean with mild detergent and let the cover dry on the line.

Common Mistakes to Avoid

• Measuring the old cushion instead of the actual furniture. Old foam compresses, so the seat reads short by half an inch or more.
• Rounding down. Round up to the nearest quarter-inch — fabric and foam compress slightly during finishing, and the extra hair of the room reads as a perfect fit.
• Skipping the paper template on curved or angled seats. Trapezoid, clipped-corner, and bay window pieces rarely measure symmetrically in real life.
• Choosing fabric by photo only. Order swatches when the room palette matters — screen color isn't the room color.
• Picking memory foam. It's a bedding foam, not a seating foam — high-density polyurethane (for indoor) or dry-fast (for outdoor) holds shape under repeated sitting.

Before You Place the Order — Quick Checklist

☐ Measurements double-checked in inches, written down with width, depth, and height labeled.

☐ Template traced on paper for any non-rectangular shape (bay window, trapezoid, clipped corner, curved chair).

☐ Fabric selected with the actual climate and use case in mind — Sunbrella performance fabric for the right job.

☐ Securing option chosen — ties, drawstring, or buckle straps — based on wind, kids, or pet exposure.

Frequently Asked Questions

How do I keep my bench cushion from sliding?

Order custom ties or non-slip backing. Every custom cushion is built to your exact measurements with your choice of Sunbrella or Agora performance fabric, and the perfect-fit warranty backs the finished piece. If your situation is unusual — a curved seat, an angled bench, a nonstandard shape — reach out to customer-care with a photo and dimensions before ordering, and the team will confirm the right build.

We have an odd-sized breakfast bench — can we order a custom size?

Absolutely. Every cushion is custom-made to your exact measurements. Odd, unique, and non-standard sizes are all part of the standard offering. Share your dimensions at the sizing step of the product page. If the bench has an irregular shape, upload a sketch or photo. Customer care reviews every order before the fabric is cut. If anything reads unusual for the shape you've selected, they'll reach out to confirm.

For personalized help, call +1 720-627-7225 or use the live chat icon on the ZIPCushions site. The team walks people through nonstandard shapes every day.

How can I order a custom cover or cushion?

Start on the product page that best matches your shape, enter your measurements, pick your fabric, and add to cart. If our standard options don't cover your shape, use the Custom Covers or Custom Shape product page and upload your sketch. On the product page, you'll enter your measurements at the sizing step, pick your fabric or PVC weight, and choose any securing details — ties or non-slip backing on cushions, drawstrings or buckle straps on covers.

Add the item to the cart and check out; customer care reviews the numbers before the fabric is cut, and they'll email or chat with you back if anything looks unusual for the shape you selected. If your furniture doesn't match one of the standard product pages (a custom L-shape sectional, a hexagonal fire pit, an unusual bench), use the Custom Shape product page and upload a paper sketch with dimensions marked on each edge.

How can I specify custom angles for my design?

Upload a paper template or a sketch with measurements during checkout — our team will match the angles exactly. If you have a complex shape, our customer-care team will follow up with you before cutting. The template method works better than a written angle in almost every case — a paper trace captures the exact curve or corner, including any small irregularities that a pure geometry description would miss.

Butcher paper or kraft paper both work; lay a sheet over the seat or the furniture footprint, trace the outline with a pencil pressed against the edge, and mark the top edge (or the side that faces the wall) so the finished piece comes back oriented correctly. For furniture with multiple angled sides — bay window seats, trapezoidal benches, clipped-corner ottomans — trace each side separately and label each edge with its dimension in inches.

Customer care usually catches missing dimensions during order review, but a labeled template makes the intent unambiguous and shaves days off the back-and-forth.

Can I communicate with customer support?

Yes — use the live chat icon on any page, or email customer care. Response time is usually within a few hours during business days. The live chat icon in the bottom-right of any page connects you directly to customer care during business hours — response time is usually under an hour on weekdays. Email works too and gets a response within one business day.

For measurement questions, sharing a photo (with a tape measure laid across the piece) gets you the fastest answer — a picture with numbers on it clears up in seconds what a written description takes ten emails to nail down. If you're mid-order and something looks wrong, message customer-care with your order number and the specific concern; the team can pause the order before the fabric is cut.
