Litbuy Sizing Guide: How to Get the Right Fit Every Time in 2026

Introduction: Why Sizing Is the #1 Challenge
If there is one topic that generates more Litbuy spreadsheet questions than any other, it is sizing. The gap between what a buyer expects and what arrives is almost always a sizing issue. Asian market sizing runs significantly smaller than US sizing — an XL from many Litbuy spreadsheet categories may fit like a US medium or even small. This is not a defect or a scam; it is simply a different sizing standard. The good news is that with the right measurement approach and an understanding of how to read product size charts, you can get the right fit consistently. This guide covers how to measure yourself, how to interpret size charts for each category, and the category-specific sizing quirks that experience has taught us.
How to Measure Yourself Correctly
Accurate measurements are the foundation of successful Litbuy spreadsheet ordering:
1
Chest/Bust: Measure around the fullest part of your chest, keeping the tape horizontal and snug but not tight. Breathe normally — do not puff out or suck in.
2
Shoulder Width: Measure from the edge of one shoulder to the other across your back. This is easiest with someone helping you.
3
Sleeve Length: Measure from the shoulder seam point to your wrist bone with your arm slightly bent.
4
Waist (for pants): Measure around your natural waistline — the narrowest part of your torso, usually about an inch above your belly button.
5
Hip (for pants): Measure around the fullest part of your hips and buttocks.
6
Inseam: Measure from the crotch seam to the bottom of your ankle bone along the inside of your leg.
7
Foot Length (for shoes): Stand on a piece of paper, mark the tip of your longest toe and back of heel, then measure the distance in centimeters.
Category-Specific Sizing Tips
Each Litbuy spreadsheet category has unique sizing considerations:
| Aspect | Normal / Expected | Red Flag / Concern |
|---|---|---|
| T-Shirts | Size up 1-2 sizes from US | Check chest width and length — Asian tees run shorter in body length. 180+ GSM tees shrink less. |
| Hoodies/Sweaters | Size up 1-2 sizes from US | Check chest, sleeve, and body length. Oversized fit = size up 2; regular fit = size up 1. |
| Jackets | Size up 2 sizes from US | Account for layering. Measure shoulder width carefully — it is the hardest measurement to fix. |
| Pants/Shorts | Size up 2 sizes from US | Waist measurement is critical. Measure waist in cm, not inches. Inseam runs shorter than US. |
| Shoes | Size up 1-1.5 sizes from US | Measure foot length in cm. Add 0.5-1cm for comfort. Width: Asian standard = narrow for US feet. |
| Jerseys | Size up 1 size for authentic | Authentic jerseys fit trim. Replica fit more generously. Check chest width, not label size. |
Common Sizing Mistakes and How to Avoid Them
Avoid these frequent sizing errors:
1
Using your US label size instead of actual body measurements — US sizes are not standardized and vary between brands.2
Not converting inches to centimeters — all Litbuy spreadsheet product charts use centimeters. Multiply inches by 2.54 to convert.3
Measuring while wearing bulky clothing — always measure over thin clothing or directly on skin for accuracy.4
Ignoring the "allow 1-3cm variance" note on size charts — this is standard manufacturing tolerance, not a trick.5
Choosing size based on height and weight alone — body proportions vary, and two people with the same height/weight can need different sizes.Frequently Asked Questions
Should I always size up when ordering through the Litbuy spreadsheet?
Almost always, yes. As a general rule, size up 1-2 sizes from your US size for clothing, and 1-1.5 sizes for shoes. The exception is if you are buying from sellers who explicitly use US sizing — these are rare, but they do exist on the full catalog.
What if I am between sizes on the chart?
Always choose the larger size when between measurements. It is much easier to slightly tailor or layer a piece that is a bit big than it is to stretch one that is too small. For shoes, go up rather than down — tight shoes are unwearable, while slightly loose shoes can be fixed with insoles.
