How to Measure Your Feet Properly
Getting an accurate foot measurement is crucial for finding the right shoe size. Follow our step-by-step guide for the most precise measurements.
Prepare for Measuring
Measure your feet in the afternoon or evening when they're at their largest. Wear the type of socks you'll typically wear with the shoes you're buying.
- A4 paper or larger
- Pen or pencil
- Ruler or measuring tape
- A wall or flat vertical surface
Trace Your Foot
Place a piece of paper on a flat, hard surface against a wall. Stand on the paper with your heel against the wall and trace around your foot with a pen or pencil.
Measure Length & Width
Measure from the heel to the longest toe for length. For width, measure the widest part of your foot (usually across the ball of the foot).
- Length: Heel to longest toe
- Width: Widest part of foot
- Arch length: Heel to ball of foot
Check Both Feet & Add Space
Measure both feet as they can differ. Use the larger measurement and add 1-1.5cm (0.5-0.6 inches) for growing room and comfort.
Professional Fitting Tips
Before You Buy
- Always measure both feet - they can be different sizes
- Shop for shoes in the late afternoon when feet are largest
- Bring the socks you'll wear with the shoes
- Consider the shoe's intended use (running vs. dress)
- Check return policies for online purchases
Perfect Fit Signs
- 1cm (thumb width) space between longest toe and shoe front
- No pressure points or pinching
- Heel doesn't slip when walking
- Width feels comfortable without bulging
- You can wiggle all toes freely
Red Flags - Poor Fit
- Toes touching the front of the shoe
- Foot spilling over the sides
- Heel slipping out while walking
- Pressure points or pain anywhere
- Need to curl toes to fit
Understanding International Shoe Sizing Systems
Different countries use various shoe sizing standards. Understanding these systems helps you convert sizes accurately when shopping internationally or online.
UK Sizing System
Based on the length of the last (shoe mould) in inches, starting from size 0. Each size increment represents approximately 1/3 inch (8.5mm).
- Origins: Developed in 1856 by shoemaker Edwin Bannister
- Scale: Size 0 = 8 inches, each size = +1/3 inch
- Used in: UK, Ireland, India, South Africa
- Men's range: Typically 6-15
- Women's range: Typically 3-9
US Sizing System
Similar to UK sizing but starts from a different baseline. Men's and women's scales differ, with women's sizes running about 1.5 sizes larger than men's for the same foot length.
- Origins: Based on UK system with different starting point
- Gender difference: Women's +1.5 sizes larger than men's
- Used in: USA, Canada, Mexico
- Men's range: Typically 7-16
- Women's range: Typically 5-12
European (EU) Sizing
Based on foot length in centimetres using the Paris Point system. Each size represents 2/3 centimetre (6.67mm) increments, making it more precise than UK/US systems.
- Origins: Paris Point system from 1880s
- Scale: Size = foot length (cm) + 1.5cm × 1.5
- Used in: Most of Europe, Brazil, and many global brands
- Range: Typically 35-50
- Unisex: Same scale for men and women
Japanese (CM) Sizing
Direct measurement of foot length in centimetres, making it the most accurate and straightforward sizing system. Popular with athletic brands and increasingly used globally.
- Method: Direct foot length measurement in cm
- Accuracy: Most precise sizing system available
- Used in: Japan, Korea, many athletic brands
- Range: Typically 22-32cm
- Increments: Usually 0.5cm steps
Other International Systems
Various other countries and regions have their own sizing standards, often based on or adapted from the major systems above.
- Australian: Similar to UK but with slight variations
- Chinese: Based on foot length in mm (250mm = size 25)
- Korean: Similar to Japanese CM system
- Mondopoint: ISO standard using mm measurements

Frequently Asked Questions
Why do shoe sizes vary between brands?
Manufacturers use different lasts (shoe moulds), materials, and construction methods. A size 8 in one brand might fit like a 7.5 or 8.5 in another. Always check brand-specific sizing guides.
Should I size up or down if I'm between sizes?
Generally, it's better to size up slightly. Your feet swell throughout the day, and shoes often stretch with wear. However, consider the shoe type - athletic shoes can often run larger.
How often should I measure my feet?
Adult feet can change over time due to age, weight changes, or pregnancy. Measure at least once a year, or when you notice your current shoes feeling different.
Do width fittings matter?
Yes! Width is as important as length. Standard widths are B (narrow) or D (regular) for women, and D (regular) or EE (wide) for men. Many brands offer multiple width options.
Can I convert children's sizes to adult sizes?
Children's sizing is completely different from adult sizing. A child's size 13 is followed by adult size 1. Use our dedicated children's size charts for accurate conversions.
Are online size charts accurate?
Brand-specific size charts are generally reliable, but individual fit can vary. Check reviews, return policies, and consider ordering multiple sizes if unsure.
