You searched for a jersey, saw a number like 48 or 52, and had no idea what it meant. You're not alone. Most people shopping for jerseys today grew up with S, M, L, XL — so when a jersey size chart shows numbers like 40, 44, or 60, it stops them cold.
This guide explains the numeric system simply and completely. You'll know your size before you get to the checkout.
Why Jerseys Use Numbers Instead of S, M, L, XL
The numeric sizing system on jerseys goes back to the mid-20th century, when athletic apparel was sized the same way dress shirts and suits were — by chest measurement in inches. A size 44 jersey was literally built for a 44-inch chest. Straightforward.
As consumer clothing shifted toward the simplified S/M/L/XL system in the 1970s and 80s, most casual apparel followed. But authentic athletic jerseys — the kind worn by real teams, organized leagues, and now commemorative manufacturers — held on to the numeric system. Why? Because numeric sizing is more precise. It gives manufacturers a specific dimension to cut to, which matters when you want something that fits like a real jersey and not a generic shirt.
Today, if you're looking for a jersey that carries the same feel as what you wore on the field — your name, your number, your school colors — you're going to encounter this sizing system. Understanding it takes about two minutes.
The Numeric Jersey Size Chart (40–60)
Here's the core of the jersey size chart, translated into chest measurements and their closest modern equivalent sizes.
| Numeric Size | Chest Measurement | Modern Equivalent |
|---|---|---|
| 40 | 40–41 inches | Small / Medium |
| 44 | 42–44 inches | Medium / Large |
| 48 | 45–47 inches | Large / XL |
| 52 | 48–50 inches | XL / 2XL |
| 54 | 51–52 inches | 2XL |
| 56 | 53–54 inches | 2XL / 3XL |
| 60 | 55–57 inches | 3XL / 4XL |
One thing to know: jersey sizing tends to run slightly larger than everyday clothing. A size 48 jersey has room to layer over shoulder pads or move freely during play. That history is baked into the cut.
How to Measure Yourself for a Jersey
You need two measurements and a flexible tape measure.
Chest: Wrap the tape around the fullest part of your chest, just under your armpits and across your shoulder blades. Keep it level and snug but not tight. That number in inches is your starting point on the jersey size chart.
Shoulders: Measure from the tip of one shoulder across to the tip of the other. This matters more for football-cut jerseys, which are built wider through the shoulders.
If you're right on the border between two sizes — say, 44 inches — go up. Jerseys are meant to have some ease to them. A size 48 on a 44-inch chest will feel comfortable and authentic. A size 44 on a 44-inch chest may feel snug depending on the cut.

Should You Size Up or Size Down?
Most people should size up, not down. Here's the thinking:
If you want the classic look — the kind of relaxed, over-the-shoulder fit that actual game jerseys have — go with your chest measurement size or one above it. Jerseys are not meant to be form-fitting.
If you want a more fitted look — maybe you're displaying it, framing it, or wearing it to a reunion where you want it to sit closer — you can drop one size. But go below your measurement by more than one size and the sleeves and shoulders will pull.
Layering: If you plan to wear anything under it — a long-sleeve shirt, a hoodie — go up a size automatically. Game jerseys were always worn over undershirts and base layers. The fit accounts for that.
When in doubt, pull up the iPlayedFor size chart, enter your chest measurement, and go from there.
Sport-Specific Sizing Notes
Not all jerseys are cut the same way, even within the numeric system.
Football jerseys are cut wider through the shoulders and shorter through the body. They're designed to go over pads, which means the torso tends to run roomier than you'd expect. If you played football and remember your jersey as oversized, that's intentional — size up one if you want that same authentic feel.
Baseball jerseys are longer in the body and slightly more tapered through the torso. A size 48 baseball jersey will feel different from a size 48 football jersey, even though the chest measurement is the same. Baseball cuts assume you're tucking it in — the longer hem is part of the design.
Commemorative jerseys — the kind you'd order to honor your playing days — follow the same numeric system as game jerseys. At iPlayedFor, your jersey is built to the same cut standard used for actual team apparel. When you design it, the sizing you enter maps directly to these chest measurements, so what you order is what fits.
Frequently Asked Questions
What size is a 48 jersey?
A size 48 jersey corresponds to a chest measurement of approximately 45–47 inches and fits closest to a modern Large or XL. It's one of the most common sizes for adult men who played sports through high school and college.
What size is a 44 jersey?
A size 44 jersey fits a chest of approximately 42–44 inches, equivalent to a modern Medium or Large. It's a good fit for someone who wears a large in everyday clothing but prefers the relaxed jersey feel.
What does size 60 mean in a jersey?
Size 60 is one of the largest standard jersey sizes, designed for a chest of 55–57 inches. In modern sizing, that lands around 3XL to 4XL. If you're a big guy who played on the line, size 60 is where you'll likely land.
What size jersey should I buy for a 42-inch chest?
A 44 is your best starting point. It'll give you a comfortable, authentic fit without pulling across the chest. If you want the looser game-day feel, go to a 48.
Sizing a jersey shouldn't be the thing that stops you from owning one. You wore a number for years. You earned it. Now you can put it back on.
