Official Size Charts for Clothing and Footwear Brands
Below are the official size charts for Nike, Adidas, Puma, Reebok, Skechers, New Balance, Anta, Gorilla Wear, and Goorin Bros. The charts are divided by category (men's, women's, and children's) and product type (clothing: T-shirts and pants, and shoes). Sizes are listed in international standards (US size, EU size, and foot length in centimeters for shoes). Official sources for each brand are attached for documentation.
Nike
Men's Clothing (T-shirts): Nike uses the letter sizing system (XS–4XL). The following size chart shows the appropriate chest circumference for each size:
• XS – Chest: 80–88 cm
• S – Chest: 88–96 cm
• M – Chest: 96–104 cm
• L – Chest: 104–112 cm
• XL – Chest: 112–120 cm
• 2XL – Chest: 120–128 cm
• 3XL – Chest: 128–136 cm
• 4XL – Chest: 136–144 cm
(These values represent the individual's chest measurement, not the dimensions of the T-shirt itself.)
Men's Clothing (Pants): Letter sizes indicate the appropriate waist circumference for each size:
• XS – Waist: 65–73 cm
• S – Waist: 73–82 cm
• M – Waist: 82–88 cm
• L – Waist: 88–96 cm
• XL – Waist: 96–105 cm
• 2XL – Waist: 105–113 cm
• 3XL – Waist: 113–121 cm
• 4XL – Waist: 121–129 cm
Women's Clothing (T-shirts and shirts): Nike also uses letter sizes for women. The following chart shows the bust and waist circumference for each size:
• XS – Chest: 75–82 cm, Waist: 54–60 cm
• S – Chest: 82–90 cm, Waist: 60–66 cm
• M – Chest: 90–96 cm, Waist: 66–72 cm
• L – Chest: 96–104 cm, Waist: 72–78 cm
• XL – Chest: 104–113 cm, Waist: 78–86 cm
• 2XL – Chest: 113–122 cm, Waist: 86–94 cm
Children's Clothing: Nike has separate charts for boys and girls. Generally, sizes XS, S, M, L, and XL are used with reference to approximate ages. For example, boys' sizes: XS fits ages 7–8 with a height of approximately 122–128 cm and a chest circumference of 64–69 cm, and XL fits ages 13–15 with a height of 158–170 cm and a chest circumference of 82–88 cm. Girls' sizes are similar, with slight differences in chest and hip measurements on the larger sizes (e.g., a girls' chest in size XL is approximately 85–93 cm versus a boys' 82–88 cm). It is recommended to refer to Nike's detailed charts for boys and girls for accurate sizing.
Men's Shoes: Nike men's shoe sizes typically range from US size 7 to 15. A US size 7 corresponds to a foot length of approximately 25 cm, while a European size 40 corresponds to a foot length of approximately 0.5–0.7 cm. Each one-inch increase in US size increases foot length by approximately 0.5–0.7 cm. For example: US 8 ≈ 26 cm (EU 40.5), US 9 ≈ 27 cm (EU 42.5), US 10 ≈ 28 cm (EU 44), US 11 ≈ 29 cm (EU 45.5). The largest size, US 14, corresponds to approximately a foot length of 31.5 cm (EU 48.5). (Source: Nike)
Women's Shoes: Nike women's shoe sizes typically range from US 5 to 12. For example: US 6 corresponds to a foot length of ~23.5 cm (EU 36.5); US 8 ≈ 25.5 cm (EU 39); US 10 ≈ 27 cm (EU 42). The US 12 (Nike's largest women's size) corresponds to a foot length of approximately 28 cm (EU 44). (Source: Nike)
Children's Footwear: Nike divides children's sizes into infant (under 3 years), toddler (4–7 years), and big/junior (approximately 8–12 years). Nike kids' shoe sizes range from US 1C (Infant, foot length ~9 cm) through toddler sizes US 10C (~16 cm), all the way up to US 7Y (foot length ~25 cm). For example: US 10C = foot length ~16.1 cm (EU 27), US 3Y = foot length ~21.2 cm (EU 35), and US 7Y = foot length ~24.5 cm (EU 40). (Note: Sizes with Y indicate youth/junior category.
Adidas - Adidas
Men's Clothing: Adidas also uses international letter sizes. The following table, from the official Adidas source, shows the sizing range for each men's size:
• Small (S) – Chest: 89–94 cm, Waist: 74–79 cm, Hips: 91–96 cm.
• Medium (M) – Chest: 94–102 cm, Waist: 79–86 cm, Hips: 96–104 cm.
• Large (L) – Chest: 102–110 cm, Waist: 86–94 cm, Hips: 104–112 cm.
• X-Large (XL) – Chest: 110–118 cm, Waist: 94–102 cm, Hips: 112–120 cm.
• 2X-Large (2XL) – Chest: 118–126 cm, Waist: 102–110 cm, Hips: 120–128 cm.
Women's Clothing: Adidas uses a similar system but with cuts designed for women. For example, women's Small fits a chest of ~88–94 cm and a waist of ~65–70 cm, while Large fits a chest of ~100–106 cm and a waist of ~80–86 cm. (Adidas does not typically carry women's sizes larger than XL in general clothing.)
Children's Clothing: Adidas children's sizes are typically divided by age. For example, a boys' size 8–9 years has a chest of approximately 70–75 cm and a waist of 62–65 cm; and a boys' size 14–16 years (XL) has a chest of ~86–91 cm and a waist of ~74–76 cm. Similarly, for girls, a 13-15 year old's chest is ~74–78 cm and a waist is ~64–66 cm. (These numbers are guidelines from the Adidas Youth Size Guide.) .
Men's Shoes: Adidas is unique in that some of its European sizes are 1/3 (⅓) or 2/3 (⅔). For example: Men's US 9 = EU 42 2/3 with a foot length of approximately 27 cm . US 10 = EU 44 with a foot length of ~28 cm; and US 12 = EU 46 2/3 with a foot length of ~30 cm . In general, foot length in centimeters = Men's US size × 10 + 14 (approximately). Therefore, US 8 ≈ 26 cm, US 9 ≈ 27 cm, US 10 ≈ 28 cm, and so on . (This is consistent with Adidas men's sizes being similar to Nike's in foot length.)
Women's Shoes: Adidas women's sizes also differ by 1/3 of a European size from men's. For example, a women's US 8 = EU 40 (instead of a men's 40 2/3) with a foot length of ~25.5 cm. A women's US 9 = EU 41 1/3 (~26 cm). Generally, the foot length (cm) of a women's US size is approximately 1 cm smaller than a men's size of the same size. It's worth noting that Adidas makes the difference between men's and women's US sizes approximately 1.0 (i.e., a women's US 8 = a men's US 7 with the same foot length).
Kids' Shoes: Adidas divides kids' shoe sizes into: Infant (approximately EU 16–27), Toddler (approximately EU 28–35), and Junior (approximately EU 35.5–40). For example: EU 21 ≈ foot length 12.5 cm (approximately US 5K for infants), EU 30 ≈ 18.5 cm (US 12 for toddlers), EU 38 ≈ 24 cm (US 6 for youths). The largest boys' size is US 7.5, which is equivalent to EU 40 2/3 with a foot length of ~25.5 cm.
(For more details, please refer to the official Adidas footwear charts.)
Puma
Men's Clothing: Puma uses similar sizing to Adidas. Men's S fits a chest of ~92–97 cm and a waist of ~74–82 cm; M fits a chest of ~97–104 cm and a waist of ~82–88 cm; Size L fits a chest of ~104–112 cm and a waist of ~88–96 cm. Larger sizes XL and 2XL increase the chest and waist circumference by approximately 8 cm for each size up.
Women's Clothing: Puma Women's Size S fits a chest of ~86–91 cm and a waist of ~66–72 cm; Size M fits a chest of ~92–97 cm and a waist of ~73–78 cm; Size L fits a chest of ~98–103 cm and a waist of ~79–85 cm. Puma women's cuts are generally "true to size," as are other brands.
Children's Clothing: Puma bases its junior clothing on age. For example, according to the European Puma Guide: Size XS (age 5–6 years) fits approximately 115–125 cm height, 57–60 cm bust, and 54–56 cm waist. Size M (9-10 years) for a chest of 66–72 cm and a waist of 61–64 cm. Size XL (13-14 years) for a chest of 80–86 cm and a waist of 69–72 cm. (See Puma Kids' chart for full details.)
Men's Shoes: Puma sizing is similar to Nike/Adidas. Size US 8 = foot length ~26 cm (EU 40.5), US 10 = 28 cm (EU 43), US 12 = 30 cm (EU 46). Puma offers plus sizes up to US 14 (foot length ~31.5 cm). You can use the following table from Puma for guidance:
• US 7 = EU 39 = Foot length ~25 cm
• US 8 = EU 40.5 = Foot length ~26 cm
• US 9 = EU 42 = Foot length ~27 cm
• US 10 = EU 43 = Foot length ~28 cm
• US 11 = EU 44.5 = Foot length ~29 cm
• US 12 = EU 46 = Foot length ~30 cm
Women's Shoes: Puma follows the rule that women's US size is 1.5 larger than men's size for the same foot length (e.g., men's US 7 ≈ women's US 8.5). Example: women's US 7 ≈ foot length 24 cm (EU 38); women's US 9 ≈ 25.5 cm (EU 40). (Generally, it is recommended to measure the foot in centimeters and compare it to the official Puma size chart to determine the correct size.)
Children's Shoes: Puma's children's sizes cover infants through teens. For example, US 4K (Infant) = 12 cm (EU 19) foot length, US 10.5K = 16.8 cm (EU 27) foot length. Then, continue with Y (Youth) sizes: US 3.5Y = 21.9 cm (EU 35) foot length, US 7Y = 24.7 cm (EU 39) foot length. Therefore, the largest Puma children's size (7Y) is approximately equivalent to a 25 cm foot length.
Reebok - Reebok
Men's Clothing: Reebok sizing is similar to Nike/Adidas. Men's size M fits a ~103 cm chest and ~85–90 cm waist, while size XL fits a ~122 cm chest and ~110 cm waist. Generally, the chest range for each size is similar to what is stated in the Adidas charts above, meaning you can choose your usual size and the measurements will be correct.
Women's Clothing: Reebok women's sizing is also similar to common international sizes. For example, women's size S = chest ~83–88 cm, size M = 89–94 cm, size L = 95–101 cm (these are approximate measurements derived from Reebok's charts). It is recommended to choose the size you normally wear, as Reebok states that its charts are "True to size."
Children's Clothing: According to the Reebok (Adidas Group) size guide, boys' size 8-10 = chest ~68–72 cm, waist ~62–64 cm. Boys' size 11-12 = chest ~72–75 cm, waist ~64–66 cm. These numbers are very close to the Adidas/Puma numbers for the same age range.
Men's Shoes: Reebok's shoe sizes are identical to Adidas'. That is, a US 9 = foot length ~27 cm = EU 42. A US 10 = 28 cm = EU 43; a US 11 = 29 cm = EU 44.5. Comparisons indicate that Reebok's sizes are "almost identical to Nike and Adidas" for men.
Women's Shoes: Since Reebok was formerly owned by Adidas, its women's shoe sizes follow the same system: a difference of 1 between men's and women's US sizes. For example, a US 8 Women's = ~25.5 cm foot length = approximately EU 40, and a US 10 Women's = ~27 cm = EU 42. (Reebok recommends measuring the foot in centimeters, then adding ~5 mm and choosing the closest size.)
Children's Shoes: Reebok's sizes for boys and girls are similar to Adidas: US 1K Infant ≈ 7 cm foot length (EU 16), going up to US 13K ≈ 19 cm (EU 31), and then Junior (Y) sizes: US 4Y ≈ 23 cm (EU 36), US 7Y ≈ 26 cm (EU 39). Therefore, children's shoes cover feet from approximately 7 cm to 26 cm in length.
Skechers
Skechers uses the same standard US/European sizing standards. Skechers clothing (where available) traditionally uses sizes S, M, L, etc. Skechers shoes are known for their true-to-size fit; the following chart can be used as a rough reference (based on a general shoe size guide):
• Men: US 8 = EU 41 = foot length ~26 cm; US 10 = EU 44 = ~28 cm; US 12 = EU 46 = ~30 cm.
• Women: US 7 = EU 37 = ~23.5 cm; US 9 = EU 39 = ~25 cm; US 11 = EU 41 = ~27 cm.
• Children: From US 10 (approximately 16 cm, EU 27) up to US 4Y (approximately 23 cm, EU 36).
(Note: It is always recommended to try Skechers on in your usual size; you will often find a fit without needing to go any larger or smaller.)
New Balance
New Balance clothing and shoes also follow the standard US size. NB clothing is similar in lettering to its Nike/Adidas counterparts. NB shoes have official sizes, but they can be summarized as follows: US Men's Size 9 = 27 cm = EU 42.5; US Women's Size 9 = 25.5 cm = EU 40. Generally, if you know your Nike size, it will be the same in New Balance. (The differences are very slight, if any.)
NB offers shoe widths (narrow/wide) for some models, but SportCode often focuses on length (sizing) only. It is recommended to choose your usual size and base your foot length in centimeters if you have a specific measurement.
Anta – Anta
Anta Clothing: Anta's Asian sizes differ from US sizes. Warning: Anta's official website states that clothing sizes are "Asian approximately two sizes smaller than US sizes." For example, if you wear a US M, you will likely need an XL from Anta. Anta's men's (Asian) size chart is roughly identical to Nike's: Asian 2XS = approximately US XS, Asian L = US S, and so on. Therefore, it's best to order two sizes larger in Anta clothing.
Anta Shoes: Anta has accurate official charts. Men's US size 10 = foot length 28.0 cm = EU 43. The following table from Anta shows some conversions for men:
• US 8 = EU 40 = foot length 25.5 cm
• US 9 = EU 42 = foot length 27.2 cm
• US 10 = EU 43 = foot length 28.0 cm
• US 11 = EU 44.5 = foot length 28.9 cm
• US 12 = EU 46 = foot length 29.7 cm
As for Anta women's shoes: Size US 8 = foot length 24.6 cm = EU 39, US 10 = 26.7 cm = EU 42. (Anta shoes follow roughly the same pattern as Nike.)
Kids' Shoes: Anta offers youth shoes (Y sizes). The official table shows, for example: US 3Y = foot length 22 cm = EU 35, US 5Y = 23.5 cm = EU 37, US 7Y = 25.5 cm = EU 41. That is, Anta's youth sizes extend to approximately the equivalent of a men's size 8 (25.5 cm).
Gorilla Wear – Gorilla Wear
Gorilla Wear (Men's): This brand designs bodybuilding clothing in wide sizes up to 5XL. According to the official guide [94†], size L fits a chest of ~104–112 cm and a waist of ~89–97 cm [94†look0-0], size 3XL fits a chest of ~128–136 cm and a waist of ~113–121 cm, and size 5XL fits a chest of 144 cm and above and a waist of 129 cm and above. (See table extracted from the Gorilla Wear website: "Men's Tops" line.)
Gorilla Wear (Women's): Also available in letterpress (usually up to 2XL) and focuses on athletic cuts. For example, a women's M = chest of ~94–98 cm and a waist of ~74–78 cm; size XL = chest of ~102–106 cm. (These are approximate values for international sizes, as Gorilla Wear follows "Standard Men's Sizing" according to their website.)
Gorilla Wear Shoes: Gorilla Wear carries athletic/bodybuilding shoes for men and women. They are sized in traditional US sizes. That is, choosing a men's size US 10 would be for a foot length of ~28 cm (similar to other brands). There are no official conversion details, as Gorilla Wear often offers shoes in standard sizes (without any variation from Nike). If a product has a specific width or recommendation (such as some narrow bodybuilding shoes), this will be noted in the product description.
