Your fit. Your ride. Your size.
Birds on Bikes clothing is designed for real women and real bodies, with inclusive sizing from 6 to 24.
Use the measurements below to find your best starting size.
For padded cycling pants and bibs, start with your hip measurement.
For jerseys, tees and tops, start with your bust measurement.
Your measurements are more useful than the number on the label — and if you’re unsure, our Fit Guide will help you work out how each style should actually feel.

Size Guide — Padded Cycling Pants, Shorts & Leggings
Measure your body, not your clothing. All measurements are in centimetres.
Our cycling pants are designed to fit close to the body with plenty of stretch. Use your waist and hip measurements below to find your best fit.
| Size | Waist (cm) | Hip (cm) | Inseam / Leg Length (cm) | |||
|---|---|---|---|---|---|---|
| Short | 3/4 | 7/8 | Long | |||
| 6 | 64–71 | 89–96 | 23 | 42 | 57 | 69 |
| 8 | 68–75 | 93–100 | 23 | 42 | 57 | 69 |
| 10 | 72–79 | 97–104 | 23 | 42 | 57 | 69 |
| 12 | 76–85 | 101–110 | 23 | 42 | 57 | 69 |
| 14 | 84–92 | 109–117 | 23 | 42 | 57 | 69 |
| 16 | 90–98 | 115–123 | 23 | 42 | 57 | 69 |
| 18 | 97–106 | 122–131 | 23 | 42 | 57 | 69 |
| 20 | 104–113 | 129–138 | 23 | 42 | 57 | 69 |
| 22 | 110–119 | 135–144 | 23 | 42 | 57 | 69 |
| 24 | 116–125 | 141–150 | 23 | 42 | 57 | 69 |
Start with your hips.
For padded cycling pants, your hip measurement is usually the best measurement to use first because it helps ensure the chamois sits correctly and the garment fits smoothly through your bottom and hips.
Between sizes?
Don’t automatically size up. Check our Fit Guide for guidance based on the style and how you prefer your cycling pants to feel.
Size Guide — Tshirts & Tops
All measurements in centimetres. Measure your body, not your clothing.
Our sizing runs true to what you'd normally wear. If you know your usual size, that's a great place to start. Use the measurements below to confirm, especially if you're between sizes.
| Size | Bust (cm) | Waist (cm) | Hips (cm) |
|---|---|---|---|
| 6 | 87-90 | 72-75 | 94-97 |
| 8 | 90-94 | 76-79 | 98-101 |
| 10 | 94-97 | 80-82 | 102-104 |
| 12 | 97-102 | 83-86 | 105-109 |
| 14 | 102-106 | 87-91 | 110-113 |
| 16 | 106-111 | 92-96 | 114-118 |
| 18 | 111-117 | 97-102 | 119-124 |
| 20 | 117-123 | 103-108 | 125-130 |
| 22 | 123-129 | 109-114 | 131-136 |
| 24 | 129-135 | 115-120 | 137-142 |
Start with your bust measurement.
If your bust and waist fall into different sizes, choose the size that gives you the fit you prefer through the bust.
For a closer cycling fit, choose the size nearest your measurements. For a more relaxed fit, you may prefer the next size up.
How to Measure

Measure around the fullest part of your bust, keeping the tape level across your back.

Measure around your natural waistline. Usually the narrowest part of your torso.

Stand with your feet together and measure around the fullest part of your hips and bottom.

Measure from the top of your inner thigh down to where you'd like your shorts or tights to end.
