Sizing is the number one reason for returns and exchanges in the Litbuy spreadsheet community. The good news is that getting it right is simple if you follow a systematic approach. This guide covers foot measurement, clothing measurement, Asian sizing conversions, and category-specific tips to help you order the right size every time.
How to Measure Your Feet
Place your foot on a piece of paper against a wall. Mark the longest point of your toe and the back of your heel. Measure in centimeters. This is your foot length. Do this for both feet and use the larger measurement. Then add 0.5 to 1.0 cm for breathing room depending on the shoe type. Sneakers need less room than boots.
How to Measure Your Body
For clothing, you need three measurements: chest, shoulder, and length. Use a flexible measuring tape. Measure chest at the widest point, shoulder from seam to seam on a well-fitting shirt, and length from collar to hem. Write these down in centimeters. You will compare these directly to the seller size chart.
Asian Sizing Conversion
- Asian sizing typically runs 1-2 sizes smaller than US sizing.
- A US M is usually an Asian L or XL.
- Shoes: Asian sizing often uses EUR or CM. EUR 42 is approximately US 9.
- Always check the seller's specific chart. Do not rely on general conversion tables.
- When between sizes, size up for comfort, size down for a fitted look.
Category-Specific Sizing Tips
Different categories have different sizing quirks. Understanding these before you order prevents the most common mistakes.
- Shoes: Most reps run TTS. Wide feet should go half up. Compare insole CM to your foot length.
- Hoodies: Oversized by design. Size down for fitted, TTS for oversized, up one for boxy.
- T-shirts: Usually TTS. Oversized blanks add 2-3cm to chest. Check length if tall.
- Pants: Asian sizing often requires sizing up 1-2. Measure inseam and waist precisely.
- Jackets: Size up for puffers if you layer. Denim jackets often run slim.
- Headwear: Snapbacks are adjustable. Fitteds need exact circumference measurement.
Buy a single item in your estimated size before committing to a full haul. One test purchase is cheaper than exchanging an entire order.
What if I am between two sizes?
Size up for items you want to layer or wear comfortably. Size down for fitted styles. When in doubt, check the return policy.
Do reps shrink after washing?
High-quality reps use pre-shrunk materials. Minimal shrinkage if washed cold and air-dried. Budget items may shrink more.
Can I return if the size is wrong?
Most sellers allow size exchanges before shipping. After shipping, returns are harder. Always confirm the seller policy before ordering.
