TL;DR: Standard porch swing cushions rarely fit well because every swing has different dimensions. Custom cushions are the only way to get a true deep-seat fit that stays comfortable all summer. This guide covers how to figure out what size you need, which outdoor fabric holds up to the elements, and how to order a matching seat and back set from uscushion.com, even if you're not sure of your exact measurements yet.
You spent weeks picking out the right porch swing. You hung it up, stepped back, and thought: this is going to be the best spot in the yard.
Then you went looking for cushions.
Too short. Too thin. Only a seat pad with no back. Or the right length but completely the wrong depth. If you've ever tried to find porch swing cushions at a big-box store, you already know how that search ends. You leave empty-handed, or you settle for something that almost fits and feels like it almost fits every single time you sit down.
One of our customers, Meredith from Utah, ran into exactly this. She spotted a photo on Instagram of a porch swing with a thick, deep seat cushion and a matching back. It looked like an outdoor sofa. She loved it immediately and knew she wanted that for her own porch. The problem was she couldn't find anything like it ready-made. So she came to us with her measurements: 51 inches wide, 4 inches thick, 26.5 inches deep for the seat, and a 23.5-inch back cushion to match.
We made it. A month later, she came back to place her order.
That's what custom porch swing cushions make possible. You describe exactly what you pictured, in the size that fits your actual swing, and it gets made. It's such a practical solution once you realize it exists.
What Makes Porch Swing Cushions Different From Regular Outdoor Cushions?
Porch swings have specific needs that standard outdoor seat pads just don't address, and it's worth understanding why before you shop.
First, the size range is genuinely wild. Most porch swings fall between 4 and 6 feet wide, and seat depth varies from about 18 to 36 inches depending on the style. A cushion made for one swing won't fit another, even if they're the same brand. That's why the "standard" cushion section at any store is basically useless for swings.
Second, swings move. The back-and-forth motion means cushions slide, bunch up, and shift in ways that don't happen on a stationary chair. You need ties, Velcro, or a non-slip backing to keep everything where it belongs. Standard outdoor pads rarely include those options.
Third, most swings have a back panel. Leaning against bare wood or metal slats for an afternoon isn't comfortable, no matter how nice the swing looks. A matching back cushion completely changes the experience. It makes everything feel like a proper outdoor seat instead of something you're just tolerating.
Put those three things together and you start to see why a made-to-measure cushion is almost always the right call for a porch swing.
Seat Only vs. Seat + Back: Which Setup Do You Actually Need?
For most swings, a matching seat and back set makes the biggest difference in comfort.
A seat-only pad works well if your swing has a contoured back that's already genuinely comfortable to lean against. But if you're going for that deep, sofa-style setup that Meredith was after, the back cushion is what makes it happen. I love how much that one addition changes the feel of a swing. It instantly goes from "decorative porch furniture" to "the spot everyone wants to claim."
Here's something that surprises a lot of people: at uscushion.com, seat and back cushions are always made as separate, independent pieces. They're not attached to each other. You get two distinct cushions that sit independently on your swing, which makes them easy to remove for cleaning and easy to replace one piece at a time if needed.
Some customers also order a third or fourth piece for armrests or end panels, depending on how their swing is built. The point is you order exactly the configuration your swing needs, nothing more.
What Size Cushion Does a Porch Swing Actually Need?
Here's a general reference to start: most porch swing seats are 48 to 72 inches wide, 18 to 30 inches deep, and 3 to 4 inches thick for everyday use. Deep-seat styles can go up to 46 inches in depth for a more lounging-on-a-sofa feel. Back cushions typically run 18 to 24 inches tall.
Those are ranges, not rules. Your swing may fall outside all of them, and that's completely fine.
To get an accurate fit, measure four things:
Seat width: The inside distance from one armrest to the other.
Seat depth: From the front edge of the seat to where the back panel begins.
Seat thickness: 3 inches is a comfortable everyday fit. Go with 4 inches if you want more cushioning, or 6 inches for a true deep-lounge feel (which is what Meredith chose, and it was the right choice for her).
Back height: From the base of the backrest to the top. Measure the full height.
Not sure where to start with measuring? Check out our step-by-step cushion measuring guide, which walks through each dimension with diagrams. Or just send us a photo of your swing and we'll tell you exactly where to measure. We do this all the time, and it genuinely takes the guesswork out.
One tip worth remembering: always measure the chair frame, not your old cushion. An old cushion that's been sat on for years has compressed and warped. The frame is the honest measurement.
How to Choose the Right Outdoor Fabric for Your Swing
If your swing lives outside year-round, outdoor fabric is the only option worth considering.
Our outdoor fabric is waterproof, UV-resistant, and built to handle rain, sun, and whatever your climate throws at it. It's a woven textile, not vinyl (vinyl cracks and peels, and it looks cheap within a season), so it holds up while staying soft to the touch. Such a practical choice for anything that lives on a porch.
One thing to know upfront: outdoor fabrics come in fewer color options than indoor fabrics, about 23 colors compared to 90-plus for our indoor range. That's not something we chose arbitrarily. The waterproofing process limits how colors can be applied to the fabric. Every color in our outdoor collection is genuinely waterproof and fade-resistant, which is the trade-off.
The fabric also has a slight sheen. It's not matte. A few customers have asked about this specifically, and we'd rather mention it upfront so you're not surprised when the cushion arrives.
The best way to feel confident about your color is to order free fabric swatches before you commit. Just tell us which outdoor colors interest you and we'll send actual fabric samples to your door. Holding a swatch up against your porch railing or your swing's frame makes the decision so much easier than trying to judge color on a screen.
How to Order Custom Porch Swing Cushions
The process is more straightforward than most people expect, and you don't need to have everything figured out before you reach out.
Here's how it typically works:
Step 1: Measure your swing. Use the four measurements above (width, depth, thickness, back height). If your swing has a curved back or an unusual shape, grab a few photos too.
Step 2: Choose your fabric. Browse the outdoor collection and request swatches first if you'd like to see colors in person before committing.
Step 3: Place your order. Select the dimensions closest to yours, complete your order, and then message us to confirm your exact measurements. We'll make any adjustments before we cut anything.
Not sure about your size yet? That's completely fine. Plenty of customers send us photos first, and we help them figure out exactly what they need before any money changes hands.
Meredith spent about a month thinking it over after her first conversation with us. She came back with her measurements ready and placed her order. The cushions fit her 51-inch porch swing perfectly, and she got the setup she'd seen on Instagram. Made to her exact dimensions, in a fabric that would hold up all season.
Because at the end of the day, it's not just about having a cushion on your swing. It's about finally having a spot on your porch that you actually want to sit in. Hope this gives you a clear picture of how to get there.

Frequently Asked Questions
What size cushion do I need for a 5-foot porch swing? A 5-foot (60-inch) swing typically needs a cushion around 58 to 60 inches wide (measuring the inside of the seat frame), 18 to 24 inches deep, and 3 to 4 inches thick. Seat depth varies a lot by swing design, so always measure your specific frame rather than going by the swing's overall length. For a back cushion, measure from the base of the backrest to the top. Our measuring guide walks through each step with diagrams.
Can I order a seat cushion and back cushion separately? Yes, and this is how all our cushions work by default. Every piece is made independently. Seat and back are never attached to each other unless you specifically ask for that. You can order them together in the same transaction using the same fabric, and they'll be made to match.
Are porch swing cushions truly waterproof? Our outdoor cushions use a woven waterproof fabric that resists rain, UV rays, and mildew. They're designed to live outside. We do recommend bringing them in during extended off-season storage to get the most years out of them, but routine rain and sun exposure is exactly what the fabric is built for.
How do I keep porch swing cushions from sliding? We offer three options: fabric tie straps that attach to the swing frame, Velcro hook-and-loop fasteners, and a non-slip backing. For most swings, tie straps or Velcro work best because the rocking motion tends to shift cushions over time even when they fit well. You can request your preferred option when ordering. Our bench cushion sizing guide also covers securing outdoor cushions in more detail.
How long does it take to receive custom porch swing cushions? Production and shipping typically takes 2 to 4 weeks depending on your order details and current lead times. If you're working toward a specific date (a gathering, a long weekend, a birthday), ordering a few weeks ahead is always a good idea. Reach out before ordering if timing is tight and we'll give you a current estimate.
