Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.

A US size M legging lands at a UK 10-12, using the same letter-and-band system the womens-tops chart uses for other stretch basics.

A high-waisted legging and a low-rise legging in the identical labelled size can differ noticeably in how they sit on the body, since rise height isn't captured by the letter size at all — worth checking a specific style's rise before assuming an M that worked in one cut will feel the same in another.

Frequently asked questions

Does rise height matter as much as the size letter for leggings?

For comfort, often more — a high-waisted and low-rise style in the identical labelled size sit at completely different points on the torso, so check that specific style's rise before assuming a size that worked in one cut will feel the same in another.
