How to Measure Your Sit Bones at Home
Finding the right saddle width is crucial for comfort and performance. You can accurately measure your sit bone width at home using just a piece of cardboard and a tape measure.
Cardboard Guide
Prepare the Cardboard
1.
Prepare the CardboardFind a piece of corrugated cardboard (the thicker the better). Place it on a hard, flat surface like a wooden bench, a sturdy chair, or a stair step. Avoid soft surfaces like a couch, as they won't provide a clear impression.
2.
Create the ImpressionSit directly on the cardboard. Lean forward slightly, mimicking your riding position on the bike. You can pull yourself down slightly by grabbing the edge of the surface to ensure your sit bones press firmly into the cardboard.
3.
Measure the DistanceStand up and inspect the cardboard. You should see two oval depressions left by your sit bones. Use a pen to mark the exact center of each depression. Then, use a tape measure or ruler to measure the distance between these two center points in millimeters.

Based on a sit bone distance of 130mm and your riding posture, we recommend a saddle width around {min} - 135 mm.
Why Saddle Width Matters
When a saddle is too narrow, your sit bones slide off the sides, placing your body weight onto the soft perineum tissue, causing numbness and pain. If it is too wide, it leads to chafing on the inner thighs. Correct measurement ensures that your skeletal structure supports your weight, unlocking comfort on long endurance rides.
