TL;DR: To measure a chaise lounge for a custom cushion, grab a rigid tape measure and measure the furniture frame (not your old cushion). Record five things: seat width, seat depth, back height, hinge point location, and your preferred thickness. Non-standard sizes like 25.5" or 24" work just fine. Write your exact numbers in the order notes when you check out. simple measure
"Trying to figure out the measurements."
That's one of the most common messages we get from customers at uscushion.com. And honestly? We get it. Measuring a chaise lounge for a custom cushion feels like it should be simple. But then you start wondering: do I measure to the very end of the frame? What about the part where it folds? What if my chair is 25.5 inches wide and the website only shows whole numbers?
Here's the good news. Once you know the five key measurements, the whole process takes about ten minutes. And if your chaise has an unusual shape, a gap in the middle, or arched backs, we've got you covered too.
This guide walks you through every step of how to measure a chaise lounge for a cushion. We'll use real examples from customers who've been exactly where you are right now.
The Golden Rule: Always Measure the Frame, Not the Old Cushion
The single most important rule when measuring for a new chaise lounge cushion? Measure your furniture frame. Never measure your old cushion.
Old cushions stretch, sag, and distort over time. The fabric loosens. The foam compresses unevenly. A cushion that was 24 inches wide five years ago might measure 25.5 inches today because the cover stretched out. If you base your new order on those numbers, your replacement cushion won't fit right.
This is a mistake even industry experts warn about. The fix is simple. Set your old cushion aside. Measure the bare frame of your chaise lounge directly. That's the surface your new cushion will sit on, and those are the dimensions you need.
One more thing: use a rigid tape measure (the kind with a metal blade that locks). A soft tailor's tape bends and curves, which can give you inaccurate numbers. A rigid tape keeps your measurement straight and true.
What Measurements Do You Need for a Chaise Lounge Cushion?
You need five measurements to order a custom chaise lounge cushion that fits perfectly: seat width, seat depth, back height, hinge point location, and cushion thickness.
Here's a quick overview before we walk through each one:
- Seat width: The distance from left to right across the seating area.
- Seat depth (or length): The distance from the front edge of the seat to the point where the back begins.
- Back height: The distance from where the back starts (at the seat break) to the top of the back frame.
- Hinge point: Where the cushion folds when the lounger reclines. This is the crease location.
- Cushion thickness: How thick you want the cushion to be, typically 2 to 4 inches.
Got those five numbers? You're ready to order. But let's make sure you get each one right.
Step-by-Step: How to Measure a Standard Chaise Lounge
Grab your rigid tape measure, a pen, and a piece of paper. If your phone is handy, take a few photos of your chaise as you go. Photos help our team confirm your measurements if anything looks unusual.
Seat Width
Place the tape measure across the seat from left to right at the widest point. If your chaise has armrests, measure the space between them. If there are no arms, measure the full width of the seat frame.
Pro tip: Some experts recommend adding an inch so the cushion fits snugly and hangs slightly over the edge. At uscushion, we make cushions to your exact dimensions. So give us the precise frame width. If you want a little overhang, note that in your order notes and we'll adjust.
Seat Depth (Length)
Measure from the front edge of the seat to the point where the back support begins. This is sometimes called the "seat length" on chaise lounges because it's often 45 inches or longer.
If your chaise has a continuous surface from head to toe (no separate back), measure from the foot end to where you'd want the back cushion to start.
Back Height
Measure from the bottom of the back section (where it meets the seat) to the top of the back frame. This tells us how tall your back cushion needs to be.
Important note: If your seat cushion and back cushion are separate pieces (not hinged together), subtract the thickness of your seat cushion from the back height measurement. Otherwise the back cushion will stick up above the frame. This only applies to separate-piece cushion sets, not hinged one-piece designs.
Hinge Point
The hinge point is where your chaise folds when it reclines. Look at the frame and find the crease or joint. Measure its distance from the foot end of the seat.
Why does this matter? Custom hinged chaise cushions need the fold in exactly the right spot. If we put the hinge 2 inches off, the cushion bunches up or gaps when you recline.
Cushion Thickness
Decide how thick you want your cushion. Most chaise lounge cushions fall between 2 and 4 inches.
If you're not sure, we'll cover thickness recommendations in the last section of this guide. For now, just note your preference.
Once you have all five measurements written down, double-check each one. Measure twice, order once. Then head to the custom chaise lounge cushion product page and enter your numbers in the order notes.
What If My Chaise Lounge Has an Unusual Shape?
If your chaise has arched backs, rounded corners, or a convex seat, take photos from multiple angles and send them to us along with your measurements. We'll draw a labeled diagram and send it back for your confirmation before we start production.
Not every chaise lounge is a simple rectangle. Some have curved tops on the back, tapered seats that are wider at the front, or split-back designs for double loungers. Standard "measure width and length" instructions don't cover these situations. But we handle them every day.
Real customer example: Mary Grace from California needed cushions for a double chaise lounge with two separate arched-top backs. The seat area was 50" wide by 54" deep. Each back section was 23" wide and 29" tall with a rounded arch at the top. Standard measurements alone couldn't capture that arch shape.
Here's what we did. Mary Grace sent us photos showing the back profile. Our team drew a labeled diagram marking each measurement point (width, height, arch curve) and sent it back for her to confirm. Once she approved, we cut the cushions to match.
Another example: Zynnia from Florida needed a convex-shaped seat cushion. Not flat, not concave, but gently curved outward. She sent a photo, we confirmed the shape, and produced it to spec.
The takeaway? If you can describe it and photograph it, we can make it. Send photos to our team through the contact page and we'll guide you through the rest.
Does a Folding Sofa or Gap Between Sections Change the Measurements?
No. Measure the total usable length in the position you'll use most. Note any gaps in your order notes, and we'll account for them during production.
This comes up more often than you'd think. Kelly from California had a folding sofa that converts into two connected chaise loungers when laid flat. The seat measured 51 inches, then there was a 1-inch gap at the hinge, then the back measured 26 inches. Total: 78 inches.
Her question was natural: "Do I adjust for the gap?"
The answer: don't subtract the gap. Measure the full 78-inch length. Then write in your order notes something like: "1-inch gap at 51 inches from foot end." We'll factor that into the cushion design so it sits flat and natural across the full surface.
If your furniture has a hinge that folds frequently, consider ordering a two-piece cushion set with the split at the hinge point. That way each piece folds independently. But if you mostly use it flat, a single piece works great.
Non-Standard Sizes: What If My Chaise Is 25.5 Inches Wide?
We make custom chair cushions in any size. Half-inches, quarter-inches, 76.75 inches long: all fine. If you can measure it, we can make it.
This confuses some customers because our website size selector shows whole numbers in the dropdown menu. Cindy from California needed cushions that were 25.5 inches wide. Glynda from Florida needed 24 inches, but the dropdown didn't show that option. Marcia from North Carolina told us flat out: "The link you sent me does not let me put in the correct size."
We totally understand. The dropdown is a starting point, not a limit. Here's how to get your exact size:
Option A: Select the closest size from the dropdown. Then write your precise dimensions in the order notes field. Something like: "Actual width: 25.5 inches, actual length: 76.75 inches."
Option B: Contact our customer service team. We'll set up a custom payment link with your exact specs already entered.
Either way, your cushion gets made to the exact size you need. No rounding up, no "close enough." Custom means custom.
How Thick Should a Chaise Lounge Cushion Be?
For most chaise lounges, 2 to 4 inches is the sweet spot. The most popular thickness for outdoor chaise cushions is 3 inches. It gives you enough padding for comfort without making the cushion too bulky for reclining.
Here's a rough guide by use case:
2 inches: Best for slim-profile chaise lounges, bench-style designs, or situations where you want a sleek look. Good if your frame already has some contouring built in.
3 inches: The most popular choice. Works great for poolside loungers, patio chaise chairs, and most outdoor seat cushions. Balances comfort and practicality.
4 inches or more: Best for indoor chaise lounges where you plan to lounge for hours. Reading nooks, living room sectionals, or custom indoor cushions benefit from the extra padding.
Not sure which thickness to pick? Here's a trick from Rofielty's measuring guide: stack a few books on your chaise seat to simulate different thicknesses. Sit on them for a minute. That gives you a feel for whether 2, 3, or 4 inches is right for you.
One more thing. If your chaise has armrests, make sure the cushion thickness doesn't push the seating surface above the armrests. That creates an awkward, uncomfortable position. Measure from the seat frame to the top of the armrest to find your maximum thickness.
At uscushion, our standard is 70D high-density foam, which holds its shape for years. If you want to explore foam options in more detail, check out our best foam for cushions guide.

Already placed your order and realized a measurement is off? No problem. Contact us within 48 hours and we'll adjust for free before production starts.
The goal is simple: measure your frame, tell us the numbers, and let our tailors handle the rest. Whether your chaise is 22 inches wide or 54 inches wide, whether the back is flat or arched, whether there's a gap at the fold or not, we make it fit.
Frequently Asked Questions
Should I measure to the very end of the chair frame or leave an inch or two?
Measure the actual frame from edge to edge. That gives us the true dimensions of the surface your cushion will sit on. If you'd prefer the cushion to stop an inch or two short of the edge, just note that in your order. We had a customer named Larry from Florida ask this exact question. Our answer: give us the full frame measurement and tell us your preference in the notes. We'll adjust accordingly.
My chaise has a gap where it folds. Do I subtract the gap from my measurement?
No. Measure the total usable length including the gap. Then note the gap size and location in your order notes (for example: "1-inch gap at 51 inches from foot end"). We'll design the cushion so it sits naturally across the full surface without sagging at the gap.
Can I order a chaise cushion in a non-standard size like 24 inches or 25.5 inches?
Absolutely. We make cushions in any size, including half-inches and odd dimensions like 76.75 inches. The website dropdown shows whole numbers as a starting point. Just select the closest option and write your exact measurements in the order notes. Or contact our customer service team for a custom payment link.
How do I measure a double chaise lounge with split backs?
Measure the seat area as one piece (width and depth). Then measure each back section separately, recording the width, height, and shape of each one. If the backs have arched or rounded tops, take photos from the front and side. Send everything to our team and we'll create a labeled diagram for your approval.
What if I make a measurement mistake after ordering?
Contact us within 48 hours of placing your order. We offer free adjustments before production begins. Just email us the corrected measurements and we'll update your order. After 48 hours, changes may still be possible depending on production status, so reach out as soon as you can.
