How to measure for the right size at home

Sit bone measurement

SQlab was the first components manufacturer to develop the saddle width system for measuring the sit bones and calculating the optimum saddle width.

How to measure the sit bones at home
1. Find a piece of cardboard size A5-A4 (corrugated cardbord works best) or order your measuring kit here
2. Place the cardboard on a flat, hard chair / bench etc.
3. Sit on it and arch your back while pushing down on your toes this will push the sit bones further out pull yourself down to increase pressure.


4. Stand up. The sit bones should have imaged themselves on the cardboard.
5. Take a marker and outline the prints and then mark the middle of each print.
6. Take a ruler and measure the distance (middle to middle).
7. Add the factor of your sitting position (see pic below +0, +1, +2, +3, +4cm) to the measurement.
The result is your SQ Lab saddle size.
If you are between two numbers always round up.

Please answer as many questions as possible
my sit bone distance (middle to middle) is :

how many kilometers do you ride a week / a month / a year
how many days a week do you ride (average)
What bicycle do you ride (Road, MTB,...)
What is your riding style(agressive, sporty, moderate....)
please also send us pictures of:
