SuperBuy Sizing Guide: How to Choose the Right Fit in Every Category

Sizing is the number one reason for disappointment on SuperBuy. Chinese sizing often differs from US, EU, and UK sizing. This guide covers every category in the SuperBuy spreadsheet and tells you exactly how to measure, what to check, and when to size up or down.

Shoes: Never trust the listed size. Always check the insole length in centimeters. Measure your foot from heel to longest toe and add 5-10mm for comfort. Most SuperBuy shoes run 0.5 to 1 full size small. If you are between sizes, size up. Check reviews for width information — some shoes run narrow.

Hoodies and Sweaters: Oversized fits are the norm. For an oversized look, order your true size. For a standard fit, consider one size down. Check the shoulder-to-hem length and sleeve length. GSM weight matters — 280+ GSM feels premium, below 200 GSM feels thin. Oversized hoodies often have 10-20 cm longer sleeves than standard.

T-Shirts: Boxy fits are wider and shorter. Standard fits are longer and narrower. For boxy fits, order your true size. For standard fits, size up if you prefer a looser feel. Check the shoulder width and chest width in the size chart. Measure your favorite tee at home and compare.

Jackets: Jackets are usually sized for layering. Order your true size unless the listing specifies slim or oversized. Check the shoulder seam position — it should sit at the edge of your shoulder. For puffer jackets, check the baffle distribution and overall bulk. Heavier jackets may add significant shipping weight.

Pants and Shorts: Waist sizing is the most critical. Measure your waist at the navel in centimeters. Compare this to the size chart. Asian sizing usually runs one size smaller than US sizing. Check the inseam for pants and the outseam for shorts. For cargo pants, check the pocket depth if you carry large items.

Headwear: Caps are usually adjustable, but check the crown depth. Deep crowns suit larger heads. Flat brims vs pre-curved brims are a style preference. For beanies, most are one-size. Check the knit density — loose knits stretch more but lose shape faster. Bucket hats should have a structured brim.

Sets: Check both pieces independently. Some sets have the top and bottom in different size charts. If one piece is oversized and the other is standard, plan accordingly. Sets are usually color-matched, but verify this in the warehouse photos.

Jerseys: Jerseys are typically oversized by design. If you want a normal fit, size down. For a streetwear oversized look, go true to size. Check the sleeve length and overall length. Mesh jerseys are usually more forgiving in fit.

Underwear: Check the waist measurement in centimeters. Asian sizing runs smaller. Size up for comfort. Pack sizes vary — 3-packs and 5-packs are common. Check the fabric blend for stretch percentage.
