The short answer
Stand on A4 paper, mark the widest points of your forefoot with the pen held vertically, then measure the straight-line distance between those marks in millimetres.
Measure both feet. If they differ, use the larger result as fit context and make sure the smaller foot still feels secure.
What you need
Five simple steps
1. Prepare a hard, flat surface
Place the paper on a floor that will not compress. Avoid thick carpet.
2. Stand naturally
Place one foot on the paper and distribute your weight normally across both feet. Measuring while seated may give a different result.
3. Mark the widest points
Identify the widest area across the forefoot. Hold the pen upright and mark each side without angling under the foot.
4. Measure in millimetres
Measure the straight-line distance between the two marks. Record the number and the time of day.
5. Repeat for the other foot
Feet are often slightly different. Measure both rather than assuming they match.
How to improve consistency
Repeat the measurement twice and compare the results. Keep the same socks, stance, pen angle and time of day. If the readings differ significantly, repeat rather than averaging uncertain marks.
For shoe selection, combine width with length, toe shape, heel security and how the shoe feels during movement.
What this measurement cannot tell you
Foot width alone cannot predict exact shoe fit. Brands use different lasts, internal volumes and width labels. Materials and construction also change how a shoe feels.
A home measurement is an estimate. Badger Fit can help organise this information, but it does not replace an in-person fitting or professional assessment when one is needed.
Frequently asked questions
Should I measure both feet?
Yes. Measure both and use the larger result as fit context while checking that the smaller foot remains secure.
What time of day should I measure?
Measure at a consistent time that reflects when you usually wear the footwear. Feet may feel different after long periods of standing or activity.
Does width determine my shoe size?
No. Shoe size usually centres on length. Width, shape and internal volume must be considered separately.
