How to Measure Yourself for a T-Shirt
Getting accurate measurements is the key to finding the perfect t-shirt fit. Follow these simple steps to measure yourself correctly:
Chest/Bust Measurement
The chest or bust measurement is the most important for determining your t-shirt size. To measure:
- Stand straight with your arms relaxed at your sides
- Wrap a measuring tape around the fullest part of your chest/bust
- For men, this is typically at nipple level
- For women, measure around the fullest part of your bust
- Keep the tape parallel to the floor and snug, but not tight
- Take a normal breath and record the measurement
Measuring Tip
If you don't have a measuring tape, use a piece of string and then measure it against a ruler.
Waist Measurement
While not always necessary for t-shirts, waist measurements can help determine if you need a more relaxed fit:
- Find your natural waistline (the narrowest part of your waist, typically above your belly button)
- Wrap the measuring tape around your waist at this point
- Keep the tape snug but not digging into your skin
- Take the measurement while standing in a relaxed position
Height and Weight
These measurements can help refine your size recommendation, especially for length considerations:
- Measure your height without shoes
- Weigh yourself on a flat surface without heavy clothing
- These factors help determine if you might need a "tall" size variant
Understanding Fit Preferences
Regular Fit
Standard fit that works for most body types. Not too tight or too loose, with a classic silhouette.
Slim Fit
More contoured to the body shape. Narrower in the chest and waist for a more tailored appearance.
Loose/Relaxed Fit
More room throughout the garment for a comfortable, casual look. Great for layering or a more relaxed style.

Frequently Asked Questions
Why do t-shirt sizes vary between brands?
T-shirt sizes can vary between brands due to several factors. Each manufacturer may use slightly different measurements for their standard sizes, a practice called "vanity sizing." Additionally, different cuts, fabric compositions, and design intentions (fitted vs. loose styles) all contribute to size variations. International brands may also use different regional sizing standards as their baseline.
Should I measure myself with or without clothes on?
For the most accurate measurements, you should measure yourself while wearing lightweight, form-fitting clothes, similar to what you'd wear under a t-shirt (like a thin undershirt). Don't measure over bulky clothing, as this will add extra inches and lead to an oversized recommendation. If measuring directly over skin, don't pull the measuring tape too tight.
How do I determine the right t-shirt length?
T-shirt length is typically proportional to the chest/bust size, but height is an important factor too. If you're taller than average (over 6'1" for men or 5'8" for women), you might want to look for "tall" sizes that offer extra length. Similarly, if you're shorter than average, standard t-shirts might be too long. Our calculator factors in your height when available to suggest appropriate sizing.
What if I'm between sizes?
If you find yourself between sizes, consider your personal preferences and the specific brand. For a more comfortable fit, size up. If you prefer a more fitted look, choose the smaller size. Also consider the fabric – 100% cotton t-shirts may shrink slightly after washing, while blends with synthetic fibers typically maintain their size better.
