Hey there, fellow frame shop owners, DIY enthusiasts, and anyone tired of settling for one-size-fits-all frame moulding—let’s cut to the chase: if you’ve ever stared at a wall that’s just a little too big, a custom art print that’s not standard, or a gallery wall that’s thrown off by weirdly sized pieces, you’ve probably wondered, “Can I order custom-sized PS frame moulding?” PS Frame Moulding
I’m right here with you, since I’ve been running a PS frame moulding supply company for the past 8 years, and I get the headache of off-the-shelf moulding that’s either too narrow, too thick, or way too long for your project. Let’s break this down straight, no corporate jargon, and zero fluff.
First off: What is PS frame moulding, anyway? If you’re new here, PS stands for Polystyrene—it’s that lightweight, rigid, affordable stuff that’s used for most mass-produced frames these days. It’s way easier to cut, shape, and paint than solid wood, and it’s resistant to warping, which is a huge win for anyone dealing with humid areas like bathrooms or basements. But for a long time, people thought you could only get it in pre-cut lengths and standard profiles—wrong.
Let’s start with the basics: Can you actually order custom sizes? The short answer is YES, and it’s way more common than you think. I’ve had small frame shops walk in here panicking because they needed 12 feet of 1.5-inch wide moulding for a giant canvas, and big interior design firms hitting me up for 10,000 feet of 2-inch thick moulding for a hotel lobby gallery wall. The catch? It’s not just “tell me what length you want”—there’s a little science here that makes it work, and I want you to know that so you don’t waste time or money ordering something that doesn’t fit.
Let’s talk about how custom PS moulding is made, because that’s where a lot of people get confused. Polystyrene is a thermoplastic, right? That means it melts when heated and sets when cooled. So when you order a custom profile or custom dimensions, here’s the process: We first create a custom extrusion die—think of it like a mold that shapes the melted polystyrene into the exact profile (the edge style, like a classic flat, a decorative scoop, or a modern bevel) and cross-section (width and thickness) you need. Then, we pull the molten polystyrene through that die, cool it down to lock in the shape, and cut it to the exact length you specify.
Wait, so why can’t I just cut regular moulding to size myself? Great question. If you’re doing a small project, cutting stock moulding to fit a frame is fine— but here’s the problem: when you cut stock, you’re dealing with pre-set dimensions that aren’t made for your specific art. For example, if you have a 48×72 inch painting, stock moulding only comes in 48 or 72 inch lengths, which would leave you with weird gaps or waste. Custom lets you get moulding that’s exactly the length you need for the cuts—no waste, no trimming down to the wrong size.
Also, custom sizing isn’t just length. You can get custom cross-sections, too. Let’s say you want a moulding that’s 2 inches wide and 0.75 inches thick, instead of the standard 1.5×0.5 inches that’s in every big box store. That’s where PS really shines—because it’s easy to adjust the extrusion process to make thicker or wider profiles without a huge cost jump. Solid wood would require way more labor and material to make a custom cross-section, but PS is lightweight, so it’s cheaper to produce and pass those savings to you.
Now, let’s get into the details that matter when ordering custom: What specs do you need to give? I’ve seen so many people miss this and end up with moulding that doesn’t work. First, the cross-section: that’s width (the horizontal measurement, from front to back of the moulding) and thickness (the vertical measurement, how tall it is off the wall). If you’re framing a thin poster, you don’t need thick moulding—if you’re framing a heavy, thick canvas, you need enough thickness to hold the frame’s hardware. Then, the profile: do you want a plain edge, a carved detail, a molded ridge? We can even do custom painted finishes, like matte black, gold leaf effect, or even wood grain finishes that look like solid wood (no one will tell the difference unless you chip it, and even then it’s fixable).
The big one: length. Wait, PS moulding is usually sold in coils, right? No—custom is usually cut straight, but here’s the thing about thermoplastics: if you need a really long length (like 15 feet for a wall spanning a whole room), we can extrude it in continuous lengths up to 20 feet, which means no butt joints in your frame. That’s a huge upgrade over stock moulding, which usually comes in 8 or 10 foot lengths, so you have to splice them together.
Now, let’s talk about cost, because I know you’re thinking “this has to be expensive.” For custom PS moulding, it’s actually way more affordable than custom wood moulding. The extrusion die is the initial cost—usually a few hundred bucks, but if you’re ordering more than 500 feet total, that cost gets spread out so it’s almost negligible. For small orders, like a hobbyist making 10 custom frames, the die cost is a one-time fee, but many suppliers will waive it if you meet a minimum order (I do that for my regular customers, because I want them to come back). Compare that to custom wood moulding, where each custom profile can cost 2x or 3x as much, and you can see why PS custom is a no-brainer.
Wait, but what about minimums? Some suppliers will make you order 1,000 feet, but I’ve worked with small shops and even people making a few frames, so my minimum is 50 feet—so you don’t have to commit to a huge stock if you’re just testing a project. That’s something I wish more suppliers offered, so definitely ask about minimums before you order.
Let’s also bust a myth: Custom PS moulding isn’t lower quality than stock. The process is the same—we use high-density PS (not cheap, flimsy stuff) for all custom orders, so it’s just as durable, if not more, than the mass-produced stuff. The only difference is that it’s made just for your specs. I’ve had customers tell me their custom PS moulding has held up for 5 years with no warping, no fading, even in a kitchen with lots of steam.
Now, when should you go custom? Let’s use a real example: I had a customer last month who was framing a 60×84 inch original watercolor. The standard moulding for that size was 1.5 inches wide, but she wanted a 2.5 inch wide frame to make the art stand out. If she ordered stock, she’d have to buy 8 feet of moulding, cut it down, and waste 3 feet. With custom, we made her 11 feet of 2.5 inch wide moulding, cut to exactly the lengths she needed, so she had zero waste and the exact look she wanted. Another example: a friend who runs a gallery wanted a series of 10 frames, each with a different size print, but all the same 1.25 inch thick moulding. Custom meant he didn’t have to buy 10 different stock profiles—we made the same cross-section every time, so all his frames matched perfectly.
What should you avoid? Don’t mix custom with random sizes. If you need a custom profile, make sure you have exact measurements for your art or wall—measure twice, cut once, right? Also, if you’re ordering custom painted finishes, order a sample first. PS takes paint really well, but sometimes the color can look different in the extrusion, so a $5 sample can save you from ordering 50 feet of the wrong shade.
Wait, what about shipping? Custom moulding is usually straight, so shipping is cheaper than if you had to cut it, but since it’s longer than standard stock, some carriers have size limits. That’s why I work with carriers that specialize in long lengths, so my customers don’t get hit with extra fees. I also offer local pick-up for people who are close, so they can skip shipping entirely.
Now, let’s get to the next step: If you’re ready to order custom, what do you need to do? First, get your exact specs: cross-section (width x thickness), length total, profile, finish. Then, reach out to your supplier—don’t be shy, tell them your project size, how many feet you need, and if you have a tight budget. A good supplier will walk you through the process, explain the die costs, minimums, and give you a quote in 24 hours.
Wait, I should mention that I’ve had some bad experiences with suppliers that lie about custom moulding—they say they do custom, but really they just cut stock moulding to length, which isn’t real custom. Real custom is made from scratch to your dimensions, so make sure your supplier can show you the extrusion process, or give you a sample of their custom moulding before you order. That’s how you know it’s legit.
Another thing: PS moulding is recyclable, right? Most custom orders are made from recycled PS, so if you’re into eco-friendly projects, custom PS is a great choice. I use 30% recycled material in all my custom moulding, so it’s better for the planet too.
Let’s wrap this up. The answer to “Can I order custom-sized PS frame moulding?” is a resounding YES. It’s affordable, durable, customizable to every size and profile, and way more practical than settling for stock that doesn’t fit. Whether you’re a small frame shop, an interior designer, or a hobbyist doing your first gallery wall, custom PS moulding is worth the investment to get exactly what you need.
