Frequently Asked Questions

How do I accurately measure my foot length at home?
+
To measure your foot accurately, stand on a piece of paper against a wall with your heel touching the wall. Mark the tip of your longest toe on the paper. Measure the distance from the edge of the paper (heel) to the mark (toe) using a ruler. For best results, measure in the afternoon when feet are slightly larger, and measure both feet — use the larger measurement for sizing.
Should I size up or down if I’m between two sock sizes?
+
If you fall between two sizes, it’s generally recommended to size up for regular and loose-fit socks to ensure comfort. However, for athletic or compression socks, sizing down may provide better support and prevent slipping. Consider the sock material too — cotton tends to stretch, while synthetic blends maintain their shape better.
Why do sock sizes differ between brands?
+
Sock sizes vary between brands due to different manufacturing standards, materials used, and target markets. Some brands run larger or smaller based on their country of origin and sizing conventions. Our calculator provides standard sizes, but we recommend checking brand-specific size charts when available and reading customer reviews for insights on fit.
Can I use this calculator for compression socks?
+
Yes, our calculator includes an athletic/compression sock option that adjusts the sizing recommendation accordingly. However, for medical-grade compression socks, you may need additional measurements like calf circumference and ankle circumference. Always consult with a healthcare provider for therapeutic compression wear to ensure proper fit and compression levels.
How often should I re-measure my sock size?
+
For adults, foot size typically remains stable, but it’s good to re-measure annually or if you notice changes in fit. Factors like weight changes, pregnancy, aging, or certain medical conditions can affect foot size. For children, measure every 3-4 months as their feet grow rapidly. Athletes should also check sizing periodically as intensive training can affect foot dimensions.
