If you’ve ever sourced or worked with French Terry fabric, you’ve probably had that exact question pop up at some point—maybe when you’re finalizing a production run for loungewear, testing a new hoodie design, or even troubleshooting a fabric shortage mid-order. As someone who’s been a French Terry supplier for over a decade, I can tell you this isn’t just a random, trivial question. The width of French Terry fabric directly impacts everything from cost efficiency to cut yields, turnaround times, and even the finished look of the products you’re making. Let me break this down the way I do when I’m walking a new customer through their first bulk order—no overly technical jargon, just real-world, experience-backed info that’s actually useful for your bottom line. French Terry
First, let’s get one thing straight: there’s no universal “one-size-fits-all” width for French Terry fabric. That’s the biggest misconception I run into with new clients, especially apparel designers who assume all knit fabrics follow the same standard. French Terry is a knit, looped fabric, and its width depends on three main factors: the yarn count used to make it, the weight ( GSM, or grams per square meter), and the end product it’s intended for. For context, I’ve supplied French Terry to small-batch loungewear brands, activewear manufacturers, and even home textile makers, and I’ve seen widths range from 54 inches all the way up to 78 inches in full-bulk rolls. The sweet spot for most apparel applications, though, is between 60 and 70 inches—and that’s not just a guess, that’s based on thousands of orders I’ve fulfilled over the years.
Let’s dig into why that range matters. If you’re making hoodies or sweatpants, for example, a 60-inch width is ideal. Why? Because a standard adult hoodie front and back panel can be cut from a single 22-inch width of fabric, and with 60 inches, you can easily fit two hoodie panels side by side, plus a few extra inches for seam allowances and selvages (those tight, finished edges along the sides of a bolt that prevent fraying). The selvage is a non-negotiable detail here—most mass-produced French Terry I see cuts out selvages before shipping, but at our shop, we leave them intact because they add structural integrity during cutting and sewing. When you’re working with a smaller width, like 54 inches, you have to stack panels side by side more tightly, which increases the risk of cutting errors or fabric waste. I had a client a few years ago who switched to 54-inch French Terry to save a few cents per yard, and their cut yield dropped by 12% because they had to piece panels together to fit. That ended up costing them far more than the per-yard savings.
On the flip side, widths over 70 inches are usually reserved for heavyweight, industrial-grade French Terry, or technical fabrics for performance outerwear. We supply a specialized 72-inch heavyweight French Terry (around 320 GSM) to a company that makes weighted blankets and outdoor layering pieces—they need the extra width to fit large blanket panels without horizontal seams, which would disrupt the uniform texture and reduce the weight distribution. For most apparel makers, though, widths over 70 inches come with a catch: the looser the fabric (which French Terry often is), the more likely it is to stretch or sag when you’re handling it at a cutting table. I once had a test roll of 78-inch lightweight French Terry that came back from the finishing line with a 2-inch stretch across the entire width, which made it impossible to cut perfectly aligned panels. We had to rework the entire roll, which pushed the order back two weeks and ate into our profit margin—so now we only go that wide for pre-stretched, heavyweight runs where stretch isn’t an issue.
Another thing to consider is the difference between flat width and usable width. This is something I always explain to new customers, because it’s a trick that a lot of suppliers use to lowball quotes. The flat width is the total measurement across the entire bolt, including selvages, gaps, or any folded sections along the edges. The usable width is what matters for production—this is the space between the two selvages that’s free of defects, holes, or uneven tension. For example, a 60-inch flat width French Terry roll usually has a 58-inch usable width, because 1 inch of selvage on each side is cut away before cutting panels. At our shop, we always list usable width on our order confirmations, not just flat width, because we want our clients to know exactly how much fabric they’re working with—no hidden surprises. I’ve had small brands come to us after a bad experience with another supplier who quoted 60-inch width, but their usable width was only 55 inches, which meant they had to order 10% more fabric to hit their production numbers.
Now, how does fabric weight tie into width? Lightweight French Terry (around 150–200 GSM, perfect for t-shirts, loungewear shorts, or summer hoodies) almost always comes in the 60–64 inch usable width range. That’s because lightweight yarns are more pliable, and they’re easier to knit at a moderate width without stretching out of shape. Heavyweight French Terry (250–400 GSM, for thick hoodies, sweatpants, or outerwear liners) is usually knit at 66–72 inches, since the heavier yarn requires more space to maintain the loop structure without creating tight, uncomfortable fabric. I learned this early on when I was working with a mill to develop a custom 300 GSM French Terry for a major activewear brand—we tried knitting it at 60 inches, and the tight width compressed the loops, making the fabric feel stiff instead of soft and plush. Once we expanded the width to 68 inches, the loops opened up perfectly, and the stretch and breathability matched exactly what the brand wanted.
Selvage type also plays a small role here. Most French Terry has standard cotton selvages, which are narrow (about ½ inch on each side) and don’t add much to the usable width. But some luxury French Terry, which is often used for high-end designer loungewear, has reinforced selvages to prevent stretching during sewing. Those reinforced selvages can be 1–2 inches wide, so you lose a little bit of usable width—usually around 2 inches total, or 1 inch per side. That’s why we always note on our product pages if a run has reinforced selvages, so our clients can adjust their cut plans accordingly.
I get a lot of questions about custom widths, too. Can you get French Terry in a specific width, like 58 inches or 70 inches, for a specific production run? The short answer is yes, but it depends on order volume. Mills charge a setup fee for changing the width of a knit run, since they have to adjust the knitting machine’s guide bars and tension settings. For small-batch orders (under 500 yards), custom widths aren’t usually cost-effective, because the setup fee adds $0.15–$0.20 per yard to the total cost. But for bulk orders (over 2,000 yards), mills are happy to adjust the width, and the setup fee is spread out enough that it doesn’t impact your per-yard cost much. A few years ago, we had a client who needed 58-inch usable width French Terry for a line of cropped hoodies, and even though it was a medium-batch order (1,200 yards), we worked with the mill to adjust the run and kept the cost almost the same as our standard 60-inch product. That’s the kind of flexibility I aim to offer as a supplier—working with clients to meet their needs without forcing them to overspend on unnecessary customizations.
Let’s talk about real-world examples to tie this all together. Last year, we fulfilled a bulk order for a popular small loungewear brand that makes oversized hoodies and wide-leg sweatpants. They initially quoted us for 54-inch width French Terry, saying it was cheaper and fit their production line perfectly. When I walked them through the yield loss I’d seen with that width, they decided to test a roll of our 60-inch usable width French Terry. Their sample cut yield went from 88% (with 54-inch fabric) to 96% with 60-inch, which meant they needed 9% less fabric to make the same number of hoodies. That saved them over $2,000 on their 5,000-yard order—money they were able to put toward marketing and expanding their product line instead of buying extra fabric. That’s the kind of win-win that comes from understanding French Terry width, not just picking a number off a spec sheet.
Another example: we supplied a hotel linen brand with heavyweight French Terry bath towels a while back. They needed a 70-inch width to cut their towel panels without horizontal seams, which would disrupt the plush texture of the towel. We worked with the mill to adjust the knit width to 70 inches, and the result was a towel that was more durable, softer, and had a seamless, luxurious feel. The brand ended up reordering twice more that year, citing the consistent width and quality as a key factor in their sales. That’s why it’s so important to match the width to your end use—there’s no “best” width, just the right width for what you’re making.
Now, a few tips for anyone sourcing French Terry, whether you’re a first-time buyer or a seasoned production manager. First, always ask for usable width, not just flat width. As I mentioned earlier, some suppliers pad the flat width number to make their fabric seem wider than it is. Second, consider your cut yield when choosing width. A slightly wider fabric might cost a little more per yard, but if you save 10% on fabric waste, that’s a net gain. Third, if you have a unique project that requires a specific width, reach out to your supplier early—most reputable suppliers can work with mills to adjust runs, as long as the order volume makes it cost-effective.
