How to Measure Your Foot Size at Home
Measuring your foot size accurately at home takes less than 5 minutes and is the single most important step in buying shoes that actually fit. Online shoe returns are overwhelmingly driven by inaccurate size estimates. The easiest way to avoid returns is to measure your foot in millimeters, then match that length to the correct shoe size using international standards. This guide walks you through the proper measurement technique step by step, with the materials you need (just paper, pencil, and a ruler) and the most common mistakes to avoid.

What You Need
You need: (1) a sheet of A4 or Letter sized paper laid flat on hard floor, pushed against a wall; (2) a pencil; (3) a ruler or measuring tape marked in millimeters. Do not use carpet, since soft surfaces give inaccurate measurements. Wear the type of socks you plan to wear with the shoes (thin socks for dress shoes, thicker for sneakers or boots).
Step by Step Measurement
(1) Place the paper flat on the floor with one short edge against a wall. (2) Stand on the paper with your heel touching the wall. (3) Keep your weight evenly distributed on both feet and stand naturally. (4) With the pencil held vertically, mark the paper at the tip of your longest toe. (5) Step off and measure from the paper edge (where it meets the wall) to the pencil mark in millimeters. (6) Repeat for the other foot (feet are often slightly different sizes, so use the longer measurement). (7) Add 5 to 10 mm for comfort and growth room. (8) Look up the resulting length in a shoe size chart to find your size.

Common Mistakes
The biggest mistakes are: measuring without weight on the foot (feet spread when you stand, so always measure standing), using the big toe (your second or third toe is often longer), measuring once (always measure both feet), measuring with no socks or the wrong socks (changes the fit), and not adding comfort room (shoes that match your exact foot length will feel too tight).
Frequently Asked Questions
How do I use this chart?
Find your measurement in the primary column (foot length for shoes, waist for clothing), then read across for the equivalent size in every country or brand.
Are these conversions accurate?
Yes. Charts are built from standardized international size tables (Mondopoint for shoes, ISO 8559 for clothing) cross referenced against major retailer size guides.
How often is this page updated?
The sizing data on this page is reviewed quarterly and updated whenever retailers publish updated size guides.
Can I find my size without measuring?
Measuring is the only reliable method. Your clothing or shoe size can vary by one or more units between brands, countries, and even styles within the same brand.
Do these sizes work for international orders?
Yes, the charts here are the actual sizes used by international retailers. Still check brand specific size guides for best accuracy.
What if I am between two sizes?
For shoes, size up (feet swell during the day). For tops and dresses, size up for comfort. For jeans and fitted items, size down since fabric stretches.
Do men and women sizes correspond?
For shoes, yes (offset by about 1.5 in US sizing). For clothing, no. Men and women sizing systems are completely separate.
