How to Measure Bicycle Saddle Width

Great question! 
Here are the best ways to measure saddle width:

Method 1: Sit Bone Measurement (Most Accurate)

Get a piece of cardboard or sit bone measurement tool (many bike shops offer this free)
Sit on the material in your normal cycling position for 30 seconds
Mark where your sit bones (ischial tuberosities) contact the surface
Measure the distance between the two marks
Your ideal saddle width = sit bone distance + 20-25mm

Method 2: At-Home Estimation

Sit upright in a chair with feet flat
Measure the distance between your sit bones using a ruler or measuring tape from the side
Most people fall into these ranges:
Narrow (under 120mm): competitive road cyclists
Medium (120-150mm): all-purpose riders
Wide (150mm+): recreational and comfort riders

Method 3: Visual Sizing
Width appears on product specifications (usually 9-11 inches for comfort saddles)
The LONGDE Wide Bike Seat is 10" wide — excellent for recreational riders needing generous support

Pro Tips
Bring your bike to a shop — they often measure and recommend saddles for free
Remember: wider isn't always better — it should match your sit bone width
