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 and measure over underwear or close-fitting clothes.
Stand naturally and keep the tape snug, not tight.
Bust – Measure around the fullest part of your bust
Waist – Measure around the narrowest point of your waist
Hip – Measure around the fullest part of your hips
Shorts, Pants & Leggings
Jerseys & Tops
Fit Notes
- Most garments are designed with stretch for movement and comfort
- If you're between sizes, we recommend sizing up for a relaxed fit or down for a more compressive feel
- For bibs and knicks, focus on your hip and waist measurements
- For tops and tees, your bust and waist will guide the best fit
