About this calculator
This calculator converts your foot length in centimeters to shoe sizes in the Brazilian (BR) and European (EU) systems. Simply enter the measurement in centimeters and get the approximate sizes. The conversion is based on practical formulas: for Brazil, multiply the length by 2 and subtract 2; for Europe, multiply by 1.5 and add 1.5. Keep in mind these are approximate and may vary between brands and models.
Use this tool when buying shoes online, especially from international brands, or to check if a shoe size matches your foot length. It is also useful when gifting someone, if you know the person's foot length. The calculator helps avoid returns due to incorrect sizing.
Important tips: measure your foot at the end of the day, when it is slightly swollen, and wear socks similar to those you will use with the shoe. The conversion is a reference; always check the specific brand's size chart, as each manufacturer may have variations. Wider or differently shaped feet may need adjustments.
The calculator only considers length, not width. For sports or safety footwear, consult additional guidelines. Results are rounded to the nearest whole number, as common in stores.
Frequently asked questions
How to correctly measure foot length?
Place your foot on a sheet of paper, mark the tip of the longest toe and the heel, and measure the distance with a ruler. Measure both feet and use the larger measurement.
Are BR and EU sizes the same?
No, the systems are different. For example, a 26 cm foot is about size 38 BR and 40.5 EU (rounded to 40 or 41 depending on the brand).
Why can the size vary between brands?
Each manufacturer has its own size chart and last. Always check the specific brand's size chart before buying.
What if my foot is very wide?
The calculator only considers length. Wide feet may need half a size up or specific wide models. Check product details.
Do children use the same formula?
The formula is approximate for adults. For children, there are specific tables that account for growth. Consult a children's guide.
