T-Shirt Blank Quality & Fit Guide for SuperBuy in 2026

The blank — the base t-shirt before any graphic is applied — determines 70% of how a t-shirt feels, fits, and ages. In the SuperBuy spreadsheet world, sellers often advertise "premium blank" without explaining what that means. This guide breaks down the blank types you will encounter, how to evaluate them from spreadsheet descriptions, and what to check in QC photos before approving your shipment.

Fabric Types Explained

Weight Matters

In 2026, the community has settled on GSM — grams per square meter — as the standard measure of t-shirt weight and quality. A 180g tee is light and airy, good for hot climates but prone to transparency and shape loss. A 220g tee is the modern standard for streetwear, offering enough body to drape well without being hot. Anything over 250g is considered heavyweight and works best for boxy, oversized silhouettes. SuperBuy spreadsheet sellers rarely list GSM accurately, so rely on community QC photos showing the fabric thickness and drape.

Fit Types and Sizing

Fit descriptors in spreadsheets are often vague. "True to size" means nothing when the blank itself is cut oversized. Here are the fit types you will encounter and how to interpret them. A standard fit follows traditional proportions: the chest width is roughly half the total circumference, and the length lands at mid-belt. An oversized fit adds 2–4 inches to the chest and 1–2 inches to the length, with dropped shoulders. A cropped fit shortens the body significantly while keeping standard chest width. A boxy fit expands the chest and shoulder width while keeping a shorter body length.
