Next sizing at a glance

AI-generated generic editorial illustration — not a retailer product photo and does not depict the reviewed product or service. Editorial illustration supporting this section.

Next publishes its sizing information in two main places: a size guide page on the main Next site and a set of sizing articles in the Next Help Centre. Between them they cover women's, men's and children's sizing, plus homeware, pets and a selection of branded labels. For women's clothing, the guides give UK sizes alongside bust, waist and hip measurements, and the main site adds international equivalents.

For many shoppers that is enough to choose a starting size online: measure yourself, find the matching row and order from there. The guides do need supplementing in some cases. Petite and tall shoppers should use the height-based jeans and trouser lengths. Shoppers with wider feet should look at the footwear width fittings. Anyone buying a branded label sold by Next should use that brand's own chart rather than Next's.

This article is editorial guidance based on Next's official pages. It does not draw on hands-on try-on testing, and it cannot tell you how a particular garment will fit.

Where Next publishes its size guides

Next's sizing information sits in a few official locations, so it helps to know which one to open for the item you are buying.

  • The main size guide page on next.co.uk has an inch/cm toggle. It covers children's sizing, women's sizing and shoe sizing, including a foot-measuring instruction and a women's fashion size conversion table.
  • The Help Centre's sizing guides are listed as separate sections: Women's Sizing Guides, Men's Sizing Guide, Homeware Guides, Brand Sizing Guides and Pets Sizing Guide. The Women's Sizing Guides article holds the body-measurement charts for tops and dresses, jeans and trousers, and footwear.
  • The Brand Sizing Guides page carries separate charts for selected labels that Next sells.

Children's sizing is outside the main women's focus of this article, but it is published. The main page lists sizes by age with height, head, chest and waist measurements, and includes a children's shoe conversion.

The Help Centre also has a "What if the item does not fit?" article. Returns terms can change, so read that article directly rather than relying on any summary, including this one.

How to measure before you order

Next's women's guide begins by asking you to measure your body. The guide uses (i) icons beside each area, and clicking them explains how to measure that part of the body. Once you have your measurements, you choose the relevant chart from a drop-down.

  • Tops and dresses: these are sized by bust, waist and hip measurements, shown in both centimetres and inches. Take all three, not just one.
  • Jeans and trousers: these are matched to your height band rather than only a UK size. Know your height before you open this chart.
  • Shoes and slippers: Next's main size guide describes measuring foot length by putting your foot on a flat surface with your heel against a wall or straight edge. Measure in millimetres from the tip of your longest toe to your heel. Your longest toe is not necessarily your big toe.

Then compare each measurement with the chart. Next's charts are built around body measurements, so they work best when you read across from what you measured instead of relying on the size you usually buy elsewhere. Sizing varies between retailers, so a usual size is a weaker guide than a tape measure.

UK, EU and US size equivalents at Next

Show readers how to read Next's UK/EU/US/AU/RUS and letter-size conversion and footwear equivalents

The women's fashion size table on Next's main size guide page maps UK sizes to a letter size (XS to XXL) and to EU, US, AU and Russian sizes. A few rows show how it reads:

UK Letter EU US
6 XS 34 2
12 M 40 8
16 L 44 12

So if you normally shop in US sizing and wear an 8, or in EU sizing and wear a 40, this table places you at UK 12. That applies to Next's own women's fashion sizing only. Branded labels have their own charts, covered below.

Read the number columns first. The letter sizes each cover more than one UK size: UK 8 and 10 are both listed as S, and UK 12 and 14 as M. If your measurements sit near the edge of a letter band, the numeric size is the more precise guide.

Footwear has its own equivalents. The children's shoe conversion on the main page lists UK, EU and US sizes. The slipper guide in the Help Centre's women's section gives UK, EU, US and AU/NZ sizes alongside foot length in centimetres.

Treat the table as a starting point. The version reviewed for this article was cut off after the UK 24 row, and some rows were ambiguous, so confirm your size on the live Next page before ordering.

Jeans, trousers and footwear fit options

Help readers choose a trouser length option by height band and consider footwear width fittings

For jeans and trousers, the Help Centre separates length options by height band:

  • Petite: 4'11" to 5'3" (150 to 160 cm)
  • Regular: 5'3" to 5'6" (160 to 167.5 cm)
  • Long: 5'6" to 5'10" (167.5 to 177.5 cm)
  • Extra Long and Tall: both listed at 5'10" and over (177.5 cm and over)

A figure sits against each band: 69, 74, 79, 84 and 89 on the centimetre chart, and 27.5, 29, 31, 33 and 35 on the inch chart. The excerpt reviewed did not label those figures, so open the Help Centre page to see exactly what they describe. Extra Long and Tall share a height band but carry different figures, so check the product page to see which one the item uses.

On footwear, the guide goes beyond length. The slipper table gives foot length in centimetres together with width figures for Standard (D), Wide (E) and Extra Wide (EEE) fits. That means shoppers with wider feet can look for a width-specific measurement rather than simply going up a length size. Not every row in the excerpt showed all three widths, so check the live table for your size.

Strengths of the Next size guides

Judged only on what the official pages show, Next's guides have several useful features.

  • Guides by category. Women's, men's, children's, homeware, pets and brand guides are separated, and the main page and Help Centre both give centimetre and inch measurements.
  • A wide women's range in the Help Centre chart. Tops and dresses run from UK 4 to UK 26, which covers both ends of the range.
  • Body-measurement charts. Bust, waist and hip figures let you size by measurement instead of by a usual size alone.
  • Height-based length options. Jeans and trousers are broken into height bands from Petite to Tall.
  • Width fittings. The footwear guide publishes Standard, Wide and Extra Wide fits.
  • Separate brand guides. Next acknowledges that labels sized differently need their own chart and publishes them.

None of this amounts to a claim that Next's sizing is better or more accurate than another retailer's. It describes what information is available to help you choose.

Limitations and gaps in the Next size guides

The published guides have limits you should know about before relying on them.

  • Body charts, not garment measurements. The women's charts reviewed are body-measurement charts. The excerpts reviewed did not give garment-level measurements for individual items.
  • Some figures look inconsistent. In the children's table, the 7 and 8 year rows list the same inch range for height (46.1 to 48.1) even though their centimetre ranges differ (117 to 122 and 123 to 128). One Clarks row in the brand guide also shows a foot length that looks like a typo. Use the live page and do not copy figures from a summary.
  • Ambiguous labels. Letter sizes cover more than one numeric size, and the height-band columns in the trouser chart are not clearly labelled in the excerpt. The numeric size and the product page should take priority.
  • Footwear detail. The footwear table reviewed is the slipper guide, so check the product page for other shoes.
  • Brand labels differ. Branded labels use separate charts that do not match Next's own sizes.
  • Charts cannot capture everything. A chart cannot account for cut, fabric stretch or personal fit preference, so no chart can promise a perfect fit.

No hands-on testing was done for this review.

Branded labels and their separate size guides

Some of what Next sells is sized by the brand, not by Next. The Brand Sizing Guides page lists charts for labels such as Speedo, Phase Eight, Ugg and Clarks. If you are buying one of those, use the brand chart and ignore Next's own table.

  • Speedo: women's sizes use numbers such as 30 to 42, mapped to UK 8 to 20. Girls' Speedo sizes (26 to 34) map to ages from 7/8 to 15/16.
  • Phase Eight: women's clothing is charted by UK size with bust, waist and hips in centimetres. There are also XS to L sizes and S/M and M/L alternatives, each given as a range.
  • Ugg: women's and men's footwear maps UK sizes to Euro and US sizes.
  • Clarks: kids' sizing uses foot length and width fittings (D to H), with both measured in millimetres.

The rule is simple: if the product carries a brand name with its own chart on that page, size from that chart. The evidence for this article covers only the labels named above. It does not cover other high-street brands such as Uniqlo, White Stuff or Sweaty Betty, so do not assume those follow the Next or Next brand charts.

Who should size as listed and who should size differently

Size as listed from the women's chart if your bust, waist and hips all fall in the same row. This is the case the chart handles most cleanly.

Check more carefully if your measurements fall across different rows. Open the specific product page and consider which measurement matters most for that garment.

Petite and tall shoppers should use the height-based jeans and trousers lengths instead of picking a length by usual habit.

Shoppers needing larger sizes will find that Next's tops chart extends to UK 26. Availability varies by product, so check the retailer page for the item you want.

Wide-footed shoppers should look at the Wide (E) and Extra Wide (EEE) footwear widths, not only foot length.

Branded-label shoppers should use the separate brand chart. Next's own table does not apply.

Parents buying children's clothes should use age together with the height, chest and waist measurements listed on the main size guide page.

How to pick your size step by step

Give readers a repeatable checklist for choosing a size before ordering from Next

  1. Measure. Take your bust, waist and hip measurements, plus your height or foot length as relevant.
  2. Open the right chart. Choose the official Next chart that matches what you are buying: women's, brand or children's.
  3. Compare each measurement. Read across from your own figures instead of relying on a usual size.
  4. Pick the length or width option. Match your height to the trouser length band, or your foot width to the footwear fit.
  5. Re-check if needed. If you fall between sizes or you are buying a branded label, check the product page and the brand chart again.
  6. Check the help pages. Read Next's Help Centre for current returns and exchange terms before you order. This article does not state policy details.

Frequently Asked Questions

What UK size is a US 8 or EU 40 at Next?

On the women's fashion size table on Next's main size guide page, both US 8 and EU 40 sit at UK 12, listed as letter size M. That applies to Next's own women's sizing, not branded labels. The table reviewed was truncated, so confirm on the live page.

Does Next offer petite and tall lengths for jeans and trousers?

Yes. The Help Centre's Women's Sizing Guides list Petite, Regular, Long, Extra Long and Tall options by height band, starting at 4'11" to 5'3" for Petite and 5'10" and over for Extra Long and Tall. Check the product page to see which lengths a given item comes in.

Can I use the Next size chart for brands such as Speedo, Phase Eight or Ugg?

No. Next's Brand Sizing Guides page has separate charts for Speedo, Phase Eight, Ugg and Clarks. Those labels use their own sizing, so use the brand chart for them.

How do I measure my foot for Next shoes, and are wide fits available?

Next's main size guide says to put your foot on a flat surface with your heel against a wall or straight edge. Measure from the tip of your longest toe to your heel in millimetres. Your longest toe is not necessarily your big toe. The Help Centre's footwear guide lists Standard (D), Wide (E) and Extra Wide (EEE) width figures. Availability by product is not covered by the pages reviewed, so check the product page.

What should I do if I fall between two sizes at Next?

The official pages reviewed do not set out a rule for this. A sensible approach is to compare each measurement with the chart, then check the product page and consider which measurement matters most for that garment. Letter sizes cover more than one numeric size, so the number is the better guide. For current returns and exchange terms, read Next's "What if the item does not fit?" article in the Help Centre.
