Compression socks sizing guide

Why size matters

Too loose and you get little useful pressure. Too tight and you risk discomfort, pinching, or worse — especially around the cuff. Brand charts differ, so measure yourself rather than guessing from shoe size alone.

What to measure

1. Ankle circumference — usually at the narrowest point above the ankle bone
2. Calf circumference — at the widest part of the calf
3. Sometimes calf length or height for knee-high styles

Measure in the morning if your legs tend to swell later in the day, and follow the brand's own instructions.

Fit checklist

• Smooth fabric with no large wrinkles
• Cuff secure but not painfully tight
• Toes can move; no numbness or colour change
• You can put them on without extreme struggle (some firmness is normal)

When to stop and seek advice

Remove the socks and speak to a clinician if you get persistent pain, tingling, cold toes, skin breaks, or increasing swelling. Do not "push through" warning signs.
