Size Guide
Your Fit, Your Ride, Your Size
At Birds on Bikes, we design cycling clothing that’s made to fit real women — in all our glorious shapes and sizes. Our size range spans sizes 6 to 24, and each garment is thoughtfully cut for comfort, movement, and support on and off the bike.
Use the charts below to find your best fit, and remember: it’s not about the number — it’s about how you feel in it.

How to Measure
Use a flexible tape measure over underwear or close-fitting clothes. Stand naturally and keep the tape snug, not tight.
Bust – around the fullest part of your bust
Waist – around the narrowest point of your waist
Hip – around the fullest part of your hips
Shorts, Pants & Leggings


Jerseys & Tops

Fit Notes
- All garments are cut with stretch for movement and comfort
- Between sizes? Size up for a relaxed fit, size down for compression
- Bibs & knicks - focus on hip and waist measurements
- Tops & tees - focus on bust and waist measurements
