Legging Size Calculator
Find your legging size from waist and hip measurements, plus a Petite, Regular, or Tall length suggestion from your height.
Your legging size
Sizes are matched against a standard women’s activewear size chart. Individual brands commonly run an inch or two smaller or larger, so check the specific brand’s own chart when it’s available.
Getting an accurate measurement
Measure your waist at its narrowest point, usually just above the belly button, and your hip at its fullest point, typically several inches lower. Keep the tape snug but not compressing the skin, and measure standing relaxed rather than holding your breath in. Measuring over thin clothing, or bare skin, gives a more accurate result than measuring over bulky layers.
If your two measurements land in different size brackets, size to the hip — leggings that squeeze at the hip and thigh are far less comfortable, and far more prone to premature wear, than a waistband that's a touch loose.
Frequently Asked Questions
How is legging size determined?
Your waist and hip measurements are each checked against a standard women's activewear size chart (XS through XXL), and the result uses whichever measurement lands in the larger size bracket. Height then suggests a Petite, Regular, or Tall inseam length.
My waist and hip suggest different sizes — which do I pick?
Go with the larger size. A legging that's snug through the hip and thigh is uncomfortable and can wear out faster at the seams, while a slightly loose waistband is easy to manage with a drawstring, higher rise, or simple fold-over.
What do Petite, Regular, and Tall actually mean?
They're inseam-length categories keyed to height: Petite generally suits under 5'4", Regular covers roughly 5'4" to 5'8", and Tall fits over 5'8". Not every brand stocks all three lengths, but it's worth checking before assuming a Regular length will hit at the right spot on the ankle.
Why do legging sizes vary so much between brands?
There's no single legging size standard the way there is for, say, shoe sizing. Fabric stretch, rise height, and compression level all change how a given size fits, so a size chart is a starting point — always cross-check against the specific brand's own chart when it's available.
Should I size up for high-compression leggings?
Not usually — compression leggings are designed to fit snugly at your true size. Sizing up defeats the point of the compression and can cause the fabric to bag at the knees. If a specific pair runs small based on reviews, that's the exception worth sizing up for, not compression itself.
This tool is not professional fitting advice — it's a general estimate against a standard size chart. Always check a brand's specific size chart when one is available.
