The foot width calculator shows in a few seconds whether your foot is narrow, standard or wide. It divides your width by your length, and that ratio sets the label.
How do you use the foot width calculator?
- Measure at the end of the day or after training, in the socks you play in.
- Put your heel against a wall on a sheet of paper, then mark your longest toe and the widest point of your forefoot.
- Measure both feet and enter the larger values, in millimetres or inches.
Our guide to measuring your foot width has the full step by step.
What does the result mean?
The index is your width divided by your length. Below 0.36 we call a foot narrow, up to 0.40 standard, up to 0.43 wide and above that extra wide. These thresholds are a working hypothesis, because manufacturers do not use one clear width standard. That is why your complaints count as much as the number: if a boot presses on the sides, it is too narrow for you, whatever the label says.
What do you do with the result?
Take it to the boot finder, so you only see models that suit your width. If your result is wide, the best football boots for wide feet is the place to start. If a boot you already own pinches, start with where do my boots pinch instead.
Can you use the result to choose a size?
Width and length are two different things, and a wider boot is not the same as a longer one. Use the size converter to compare your length across UK, EU and US sizes, and remember that a longer boot never fixes a width problem. Pain that does not go away is a job for a GP or a podiatrist, as these tools only give fit advice.
