How measurements work
How is foot length measured?
Foot length is measured from the back of the heel to the tip of the longest toe. Stand on a flat surface with your weight on the foot being measured. Measure both feet and use the larger value. Chart conversions assume a standard toe allowance; brand lasts vary.
What do chest, waist, and hips mean for clothing?
Chest: Around the fullest part of the chest, under the arms, tape horizontal. Waist: Your natural waist, usually above the navel and below the ribs. Hips: Around the fullest part of the hips/seat. Keep the tape snug but not compressing.
Why do size recommendations vary by brand?
Size charts are not standardized globally. Different brands use different fit models, ease, and grading. Always use this tool as a starting point and check the retailer's size guide for the specific garment.
Common questions
How should I use this converter?
Pick your region and size, then read the equivalents. When in doubt, measure in centimeters and compare to the brand chart.
Why do sizes differ between countries?
Each region uses its own scale; mapping through foot length (cm) reduces error.
