Why Combat Sports Apparel Sizing Trips Up Online Buyers
A combat sports apparel sizing guide solves a problem most online shoppers know too well: you order a large, it arrives, and it fits nothing like the large already in your drawer. At Violent Poetry, we hear the same story constantly from BJJ practitioners and boxing fans who have been burned by inconsistent sizing across brands.
The core issue is that "large" is not a universal measurement. It is a label each brand applies to its own pattern. Add in the difference between a fitted training top and a relaxed graphic tee, and guessing stops working fast.
Below, we break down exactly how to measure yourself, how to read a size chart properly, and how to choose when you sit between sizes. Get this right once and online ordering becomes simple.
How to Measure for a T-shirt: Chest, Waist, Hips and Torso Length
Learning how to measure for a T-shirt takes about five minutes and a soft measuring tape. Do it once, record the numbers, and you will never guess your size again.
What You Need Before You Start Measuring
You need three things: a flexible measuring tape, a mirror, and a plain fitted t-shirt. Wear light clothing so the tape sits close to your body without digging in. Stand relaxed with your arms at your sides. Do not puff out your chest or suck in your stomach, because the tape should reflect how you actually stand.
The Four Measurements That Decide Your Size
- Chest: Wrap the tape around the fullest part of your chest, under your arms, keeping it level all the way around.
- Waist: Measure around your natural waistline, roughly at the level of your navel, without pulling tight.
- Hips: Stand with feet together and measure around the fullest part of your hips and seat.
Write each number down in both centimetres and inches. Most size charts list one or the other, and converting on the spot is where mistakes creep in.
How to Read a Combat Sports Clothing Size Chart
A combat sports clothing size chart maps body measurements to garment sizes, and reading it correctly means comparing your numbers, not your usual label.
Most charts give you two sets of numbers: body measurements and product measurements. Body measurements describe you. Product measurements describe the flat-laid garment.
| Measurement | Where to Measure | Why It Matters |
|---|---|---|
| Chest | Fullest part, under arms | Decides your base size |
| Waist | Natural waistline | Affects drape and hem |
| Hips | Fullest part of seat | Matters for longer tees |
| Torso length | Neck base to hem | Controls how low it sits |
When a chart offers a size range rather than a single number, aim for the middle of your range.
Graphic T-shirt Fit Guide: Compression, Regular and Relaxed Cuts
A graphic T-shirt fit guide comes down to three cuts: compression, regular, and relaxed. Each one changes how the same body measurement translates into a wearable size.
Compression fit sits tight against the body and is common in training wear. Regular fit follows your shape with a little room through the chest and waist. Relaxed fit adds extra space through the body and sleeves for a looser drape.
For casual graphic tees, regular and relaxed are the two you will meet most often. If you want a clean, close silhouette, size to your chest measurement exactly.
How Should a Casual T-shirt Fit?
A casual T-shirt should sit close to the body without pulling, with the shoulder seam landing at the edge of your shoulder. The hem should fall around mid-fly, and the sleeve should end mid-bicep, not at the elbow.
Fit is about drape, not tightness. A shirt that fits well moves with you and holds its shape when you stand still.
Check three points before you commit:
- Shoulders: The seam should sit at the edge of your shoulder, not past it.
- Sleeves: They should end around mid-bicep for a standard cut.
- Hem: It should land around mid-fly for a balanced look.
Get these three right and the rest follows.
Tops vs Bottoms vs Gloves: How Sizing Differs by Garment Type
Sizing works differently for every garment type, which is why one size chart never covers a full kit.
The table below shows how the same body measurement translates across the garments combat sports fans buy most often.
| Garment | Primary Measurements | Fit Tendency | When to Size Up |
|---|---|---|---|
| Graphic tee (regular cut) | Chest, torso length | Follows body with slight room | Between chest ranges, or for a looser drape |
| Graphic tee (relaxed cut) | Chest, shoulder width | Extra room through body and sleeves | Rarely, relaxed already runs loose |
| Rash guard | Chest, torso length, arm length | Snug, second-skin feel | If you dislike tight fits or have a long torso |
| Compression top | Chest, waist | Very close to body | Only if the chart explicitly says to |
| Fight shorts | Waist, hip, inseam | Roomier through thigh, adjustable waist | If you are between waist sizes or have heavy quads |
| Gi (jacket and pants) | Height, weight, chest, waist | Structured, minimal stretch | If you are between height bands |
| Hoodie or sweatshirt | Chest, shoulder, sleeve length | Looser than a tee by design | Rarely, check sleeve length instead |
A few patterns hold across most brands:
- Tops are decided by chest first, then torso length. If your chest fits one size and your torso length fits the next size up, follow the chest and accept a slightly shorter hem, or size up if you prefer a longer drape.
- Bottoms are decided by waist first, then hip and inseam. Fight shorts with an elastic or drawstring waistband tolerate a small waist mismatch; fixed-waist bottoms do not.
- Gis are usually sized by height and weight bands rather than chest and waist alone, because the jacket and pants need to move together.
Gloves are their own category. Boxing gloves are sized by weight and hand circumference, while headgear and groin guards use head and waist measurements.
For casual wear off the mats, the garment that matters most is the graphic tee. A regular cut sized to your chest measurement gives a clean silhouette; a relaxed cut sized one up gives the looser streetwear drape many martial artists prefer. Neither is a training garment, they are built for everyday life, and the fit should reflect that.
Between Sizes, Shrinkage and Care: Practical Fit Troubleshooting
Between sizes, the safest rule is to size up for a relaxed look and size down only if you want a close fit and the fabric has stretch.
But "size up or down" is only half the answer. The harder question is what to do when your measurements do not fit neatly into any single size, which is common for martial artists, who often carry muscle in the chest and shoulders that pushes them out of standard ranges.
A Simple Framework for Straddling Two Sizes
Use this order of priority when your numbers sit between two sizes:
- Chest and shoulders first for tops. If your chest fits a large but your waist fits a medium, buy the large. A tee that is tight across the chest will pull at the shoulders and look strained.
- Waist first for bottoms. If your waist fits a medium but your hips fit a large, buy the large and use the drawstring or belt to take up the slack. A waistband that digs in is worse than a slightly loose hip.
- Length last. Torso length and sleeve length are the hardest to alter, so if you are between sizes and care about drape, favour the size that gets your length right.
Body-Shape Adjustments Worth Knowing
Standard size charts assume a fairly average proportion. If yours differs, adjust like this:
- Broad chest, narrow waist: size to your chest and accept a looser waist, or look for athletic or tapered cuts.
- Long torso: size up one for tees if you dislike a short hem, and check the product measurement for body length rather than trusting the size label.
- Heavier thighs or glutes: size up in fight shorts and check the leg split, because a tight split limits movement.
Women's, Youth and Unisex Sizing
Many combat sports apparel ranges are sold as unisex, which usually means the fit is cut closer to a men's pattern. Women often find they need to size down one from their unisex size for a closer fit, or stay true to size for a looser, boxier look.
If a brand does not publish a women's or youth chart, treat the unisex chart as a starting point and use the product measurements to confirm.
Shrinkage and Care
Care affects fit more than most people expect. Washing in cold water and drying on low heat keeps a cotton tee closer to its original shape.
If you are still unsure, check the brand's size conversion notes and return policy before ordering.
Australian Competition and Consumer Commission guidance on consumer guarantees sets out your rights when a product does not match its description, which is worth knowing before any online apparel order.

Frequently Asked Questions
How do I measure myself for combat sports apparel?
Use a soft measuring tape and wear a fitted t-shirt or nothing bulky. Measure your chest at the fullest point, keeping the tape level and snug but not tight. Measure your waist at its natural crease, your hips at the widest point, and torso length from the shoulder seam to your preferred hem. Write everything down in centimetres, then compare against the size chart for that specific garment.
How should a combat sports T-shirt fit?
A casual graphic tee should sit close to the shoulders without pulling across the chest, with roughly a finger's width of room at the sleeve. The hem should land around mid-fly, and the fabric should drape rather than cling. For everyday wear, a regular or relaxed cut works well.
How do I choose the right size when I am between sizes?
Check the fabric composition first. A tee with elastane or a cotton-poly blend has more give and usually holds its shape, so the smaller size is often fine. A 100% cotton tee may shrink slightly, so the larger size is safer. Also think about how you will wear it: for a relaxed look, size up; for a fitted look, stay with your measured size.
Should I size up for a relaxed-fit graphic T-shirt?
Not automatically. A relaxed-fit tee is already cut with extra room through the body and sleeves, so ordering your normal measured size usually gives the intended drape. Sizing up an already relaxed cut can look oversized and sloppy. Check the product measurements (chest width and body length laid flat) rather than relying on the label alone.
Do combat sports apparel sizes vary between brands?
Yes. A medium in one brand can measure the same as a small or large in another, particularly across boxing, MMA and lifestyle streetwear lines. Always compare your body measurements against the specific brand's size chart rather than assuming your usual label. When in doubt, note the garment's flat-lay chest width in centimetres and compare that to a tee you already own and like.
How can I tell whether a T-shirt will shrink after washing?
Check the fabric content and care label. Unwashed 100% cotton tends to shrink slightly after the first hot wash, while cotton-poly blends and pre-shrunk cotton hold their size better. Wash cold, inside out, and line dry or tumble on low to minimise shrinkage and protect the graphic print. Following the care instructions on the label is the most reliable guide.
What is the difference between casual combat sports clothing and training apparel?
Training apparel is built for movement, sweat and contact, using performance fabrics and construction suited to the gym. Casual combat sports clothing, like graphic tees and lifestyle tops, is designed for everyday wear, comfort and self-expression outside the gym. If you want a tee for rolling or sparring, look at dedicated training gear; for wearing to and from the gym or around town, a lifestyle tee is the right choice.
