Proper yoga mat sizing ensures your head and heels stay comfortably on the mat through every pose — from Downward Dog to Savasana.
Heels hang off — Your heels slip off the mat in Downward-Facing Dog
Head off the mat — Your head leaves the mat during Savasana or supine poses
Elbows at the edge — Hands or elbows hit the floor in wide arm poses
Shoulders over the sides — Shoulders spill over in Savasana or twists
Constant repositioning — You're scooting forward or back throughout your flow
Stability loss — Feet slip off in Warrior poses due to insufficient length
Standard yoga mats are 24 inches wide. If your shoulders measure 18–20 inches or more across, consider a 26–30 inch wide mat for comfortable Savasana and prone poses. In a group class, stick to 24–26 inches to respect your neighbors' space.
