Nike Size Guide: Apparel & Footwear
Sports Nation’s sizing reference, based on Nike’s official size charts. This page is prepared by Sports Nation, not published or endorsed by Nike. Sources checked 3 November 2026.
Apparel | Footwear | Special sizing
Start with the product’s stated sizing system and fit guidance. Do not assume a size label means the same thing across men’s, women’s, unisex, children’s or Asian-sizing ranges. These charts do not confirm which sizes are in stock.
Nike apparel: measure your body
The measurements below are body measurements, not measurements of a T-shirt or other garment laid flat. Use a flexible tape and keep it horizontal.
- Chest or bust: measure around the fullest part.
- Waist: measure around the narrowest part, usually where your body bends from side to side.
- Hips: measure around the fullest part.
For standard tops, Nike advises using your chest measurement (men’s) or bust measurement (women’s) when it and your waist suggest different sizes. For standard bottoms, Nike advises using your hip measurement when hips and waist suggest different sizes. Check the individual product’s fit description and any style-specific guidance before choosing.

Nike footwear: measure your feet
Footwear uses a different system from apparel. Confirm whether the product’s size selector is UK, US men’s, US women’s or EU. Do not treat an unlabelled number as a particular sizing system.
- Tape a sheet of paper to a hard, flat surface so it cannot slip.
- Stand on it with feet shoulder-width apart and weight evenly balanced.
- Ask someone to hold a pencil straight down and mark the front toe point and the back of the heel.
- Step off and measure between the marks with a ruler. This is your measured foot length.
- Repeat for the other foot. Use the longer foot’s measurement in the official Nike chart linked below.
Important: Nike’s CM / JP size printed on boxes and labels is different from measured Foot Length (cm). Compare your measurement to the chart’s Foot Length row, not to CM / JP. Do not add a generic size adjustment. Follow official guidance for the specific shoe when provided.

Special sizing and fit
Standard apparel charts above must not be substituted for explicitly labelled Asian sizing. Use Nike’s men’s Asian tops, women’s Asian tops, men’s Asian bottoms or women’s Asian bottoms chart when applicable.
For numeric-waist trousers, use the appropriate numeric chart rather than the alpha chart. Tall and short lengths are style-specific; check the product’s inseam details. Adult charts are not children’s charts. For unisex footwear, confirm the sizing basis on the product and use the matching men’s-based or women’s-based Nike chart.
There is no blanket recommendation here to size up or down. If the size system or product-specific fit guidance is unclear, contact Sports Nation before ordering and include the product name and your measurements.
