Ruler for Measuring the Size of Shoes and Feet
 
Ruler for Measuring the Size of Shoes and Feet is a professional measuring tool set (base + ruler) that ensures shoes fit correctly and protect the health of your feet. Shoes that are too short can damage feet — and for people with reduced sensitivity (e.g., those with diabetes), the consequences can be especially harmful. With this ruler, you can precisely measure both feet and the inner length of shoes to guarantee a perfect fit.
 
Why Choose This Ruler?
Professional tool for measuring foot length and shoe inner length
Automatically adds 12 mm allowance when measuring feet — the minimum margin for healthy shoe fitting
Helps prevent foot damage caused by shoes that are too short
Essential for people with diabetes or sensitive feet
Suitable for both children and adults
Provides more accurate results than unreliable shoe sizes
How It Works
 
Measure your feet
Stand on the ruler to measure both feet.
The ruler automatically adds 12 mm to foot length.
Note the millimeter value of the longer foot.
Example: If the ruler shows 250 mm, the foot is 238 mm long and needs shoes with an inner length of 250 mm.
 
Measure the shoe’s inner length
Insert the ruler into the shoe and extend it.
Note the millimeter measurement.
 
Check the fit
If both values are the same (e.g., foot = 250 mm, shoe = 250 mm), the shoe fits.
Minor deviations are possible.
 
⚠️ Note: Length isn’t everything. Shoes can be long enough but still not fit around the ball of the foot or heel. In this case, switching to another shoe model is the only solution.
The Problem with Shoe Sizes
Shoe sizes are not standardized. Around 90% of shoe sizes are incorrect — the inner shoe length is almost always shorter than it should be.
Example: A shoe marked EU size 42 should have an inner length of 280 mm, but in reality it is often much shorter.
1 EU size = 6.67 mm (EU 42 = 280 mm)
1 UK size = 8.46 mm (UK 8 = 279.4 mm)
 
✅ With the ruler, you measure in millimeters for maximum accuracy, instead of relying on unreliable shoe labels.
Test It Yourself
Children and adults often believe their shoes fit, even if they are too short. Use the Ruler for Measuring the Size of Shoes and Feet or a simple cardboard strip 12 mm longer than your foot. If the strip bends inside the shoe, the shoe is too short.
