Shoe Size Converter

Step-by-step measuring guide

Getting an accurate foot measurement takes two minutes. Do it at the end of the day when feet are slightly larger.

### What you need - A piece of paper bigger than your foot - A pen or pencil - A ruler or measuring tape - A wall

### Steps 1. Tape the paper to the floor against a wall. 2. Stand barefoot on the paper with your heel touching the wall. 3. Mark the longest point of your foot — usually the tip of the big toe or the second toe. 4. Measure the distance from the edge of the paper (wall side) to the mark in centimetres. 5. Repeat for the other foot. One foot is often slightly longer. Use the longer measurement. 6. Add 0.5 cm if you plan to wear thick socks or if the shoe material does not stretch.

### Common measuring mistakes - Measuring while sitting. Weight-bearing feet spread wider. Always measure standing. - Marking at an angle. Keep the pen vertical, not tilted toward the foot. - Using an old shoe insole. Insoles compress and stretch over time. They are not a reliable reference. - Ignoring width. Two feet with the same length can need different sizes if one is wider. The tool above includes a width selector — use it.

How to convert centimetres to shoe size

Most online shoe size charts use one of three scales:

| Scale | Common regions | What to look for | |-------|---------------|------------------| | EU | Europe, most global brands | Whole numbers from 35 to 48. Most standardized. | | UK | United Kingdom, Ireland | Half sizes common. Typically 1-1.5 sizes below EU. | | US | United States, Canada | Men's and women's scales differ. Men's US is ~0.5 above UK. Women's US is ~1.5 above UK. |

The tool above gives you an EU size. To convert to UK or US: - UK men's ≈ EU − 33 - US men's ≈ EU − 32 - US women's ≈ EU − 30

These are approximations. Brand charts vary by 0.5-1 full size. Always check the specific brand table before ordering.

Choose the right fit for your use case

### Daily / casual shoes Sneakers, loafers, boat shoes, canvas trainers. These are the most forgiving. Your estimated size usually works as long as the brand runs true. Check the toe box — you should be able to wiggle your toes slightly.

### Sports and running shoes Running and training shoes need more room in the toe area (about a thumb's width from the longest toe to the end of the shoe). The heel should feel snug, not tight. If you run long distances, consider going half a size up from your daily size to allow for foot swelling.

### Formal and dress shoes Oxfords, derbies, heels, and loafers typically have less give. A snug heel and moderate toe room are correct — too much space causes rubbing and blisters. If the shoe material is stiff leather, expect a break-in period of 5-10 wears.

### Boots and work boots Hiking boots and work boots often run large to accommodate thick socks and foot movement on uneven ground. Your daily size may be correct, but try with the socks you plan to wear.

### Sandals and open footwear Open shoes depend more on strap placement and arch alignment than length. Use your usual size as reference and adjust based on strap adjustability.

When to adjust the estimate

| Condition | Adjust by | |-----------|-----------| | Wide foot | +0.5 size or look for wide (W/2E) models | | Thick socks (hiking, winter) | +0.5 size | | Formal / narrow last | Stick to estimate or −0.5 if between sizes | | Bunions or hammertoes | +0.5 size and look for wide toe box | | Plantar fasciitis | Use daily size; prioritise arch support insole space |

Why brand charts matter more than your usual size

Every brand uses its own last (the mould the shoe is built around). Two brands that both label a shoe as EU 42 can have different internal lengths and widths.

Examples of common variations

• Nike / Adidas: Athletic shoes tend to run true to EU size. Most of their running and training models match the standard EU scale.
• Clarks / Ecco: Often run half a size large. Many buyers size down from their usual.
• Dr. Martens: Run large. Usually go one full size down from your usual size.
• Converse: Run large. Most buyers go 0.5-1 size down.
• Timberland: Boots run large. Size down 0.5-1 for a fitted feel.
• Zara / H&M / fast fashion: Often run small. Consider 0.5 size up.
• Formal European brands (Loake, Barker, Church's): Run true to UK sizing. If you are used to EU or US sizes, check the UK conversion first.

### The reliable approach 1. Get your centimetre measurement. 2. Use the tool for an EU starting estimate. 3. Open the brand's size chart and find your centimetre length. 4. If the brand only shows EU/US/UK without cm, use the conversion table and read reviews mentioning fit. 5. Check the return policy. Free returns on the first order remove most of the risk.

Before you buy, run through this list

• [ ] Measured both feet standing, at the end of the day
• [ ] Used the longer foot measurement
• [ ] Compared centimetres against the brand's size chart
• [ ] Accounted for thick socks (if applicable)
• [ ] Selected the right shoe type in the tool
• [ ] Checked the width selector (narrow/wide matters)
• [ ] Read 2-3 recent reviews about fit for this exact model
• [ ] Verified the return policy (free returns? return window?)
• [ ] If between sizes, considered sizing up for comfort
• [ ] Tried both shoes at home on a clean surface before removing tags

Edge cases

Between sizes. If your centimetre measurement falls between two sizes, choose the larger one if you plan to wear socks or if the shoe is for sports. Choose the smaller one if the shoe is made of stretchable material or if you prefer a snug fit for formal wear.

Half sizes. Not all brands offer half sizes. If the tool suggests a half size the brand does not make, size up for comfort or down for a firm fit depending on the shoe type.

Kids' shoes. Growing children need 1-1.5 cm of growing room. Choose a size where the longest toe has about a thumb's width of space ahead. Check fit every 3-4 months.

Narrow heels / wide forefoot. If your foot shape is different from the standard last, look for brands that offer multiple width options or models designed for your foot type.

The 5-minute home fit test

Once the shoes arrive, do not assume they fit because the size number is correct. Try them properly:

1. Try both shoes — one foot is almost always slightly larger. 2. Wear the socks you plan to use with that shoe type. 3. Stand up and walk for at least two minutes on a clean, non-carpeted floor. 4. Check the heel — it should not lift more than a few millimetres when you walk. 5. Check the toes — you should be able to wiggle them slightly. If they touch the front when standing, the shoe is too small. 6. Check width — if the upper bulges over the sole edge, the shoe is too narrow. If your foot slides inside, it is too wide. 7. Check the arch — if you feel pressure under your arch, the insole shape may not match your foot.

### Red flags - Numbness or pinching after 30 seconds - Heel slippage > 5 mm - Toes curled or pressed against the front - Visible bulging at the sides - Impossible to lace comfortably (laces too tight or too loose near the tongue)

### If the fit is not right - Too small overall → return and go half to one size up - Too narrow → look for a wide (W/2E) version of the same model - Too wide / heel slips → try a half size down or a model with a narrower last - Pinches only in one spot → could be a manufacturing defect; try a replacement first

Keep the box and tags intact until you are sure. Walk on clean, dry surfaces only.
