Find your Under Armour size
Measure your body (not a garment) with a soft tape, snug but not tight.
Enter your measurements to see your Under Armour size.
Fit tip: Under Armour runs small with a slim athletic cut, so size up for a relaxed fit. Compression styles are meant to feel tight.
How to measure
- Chest / bust: around the fullest part, keeping the tape level.
- Waist: around the narrowest part, usually at the belly button.
- Hips: around the widest part of your seat.
- Foot length: stand on paper, mark from heel to longest toe, then measure the line.
Use a soft tape over light clothing, snug but not tight.
Under Armour size guide at a glance#
The shoe charts below cover men's US 7 to 16 and women's US 5 to 12, with UK and EU conversions and foot lengths in inches and centimeters in every row. Clothing is sized by chest, waist and hip in both units, with separate youth charts. Measure first, then match the row.
Do Under Armour shoes run small? Under Armour lists its shoes as true to size, but they are cut like performance shoes: snug through the midfoot with a close toe box. If you're between sizes, have wide feet, or wear thick athletic socks, go up half a size. Matching your measured foot length in the chart beats reusing a size from a casual brand.
What do Compression, Fitted and Loose mean? They are Under Armour's three apparel cuts, not sizes. Compression sits skin-tight, Fitted follows the body without squeezing, and Loose hangs relaxed. Pick your normal size from the charts and choose the cut for the feel you want; only size up in Compression if you dislike a tight fit.

Frequently asked questions#
Do Under Armour shoes run true to size?#
On paper, yes, but the athletic cut fits snug through the midfoot and toe box, and plenty of buyers go up half a size, especially for wide feet or thick socks. Measure your foot and use the chart for the model you're buying rather than guessing from another brand.
How do I measure my feet for Under Armour shoes?#
Place a piece of paper on a flat surface against a wall. Stand on the paper with your heel touching the wall. Mark the tip of your longest toe, then measure the distance from the wall to the mark. Use this measurement to find your size on the Under Armour size chart.
Are Under Armour sizes the same for men, women, and kids?#
Under Armour uses different sizing for men's, women's, and kids' products. It's important to consult the appropriate size chart for each category to ensure you get the correct fit.
How do I convert Under Armour sizes to other sizing systems?#
Under Armour size charts include conversions between US, UK, and EU sizes. Use these charts to find the equivalent size in your region.
What should I do if I'm between sizes?#
If you're between sizes, consider the fit style you prefer. Under Armour offers different fits such as Compression, Fitted, and Loose. For a tighter fit, choose the smaller size; for a looser fit, select the larger size.
Sizing tips#
- Measure first: chest, waist and foot length in centimeters settle most sizing questions faster than brand comparisons.
- Check the cut before sizing up: Compression is meant to feel tight, and going up a size defeats it. Fitted and Loose follow normal sizing.
- Read style notes: some models fit differently; product pages and reviews usually say so.
- Convert from a brand you know: the shoe size recommender turns the size you wear in another brand into your Under Armour size.
