T-Shirt Size Guide: How to Measure for the Perfect Blank Tee Fit
Ordering a "Medium" from three different blank tee suppliers can get you three different shirts. Block measurements vary by brand, by fabric (Pima cotton behaves differently than open-end cotton), and even by fit family within the same line. If you've ever reordered a style you already own and had it arrive looser or shorter than expected, the label size wasn't the problem — the measurements behind it were.
This guide skips opinions about "true to size" and gives you the actual numbers: how to measure a shirt you already own, how to read a size chart correctly, and how Blank Mind's own block compares across sizes so you can buy once and reorder with confidence.
Why the Label Size Lies More Than You Think
US apparel sizing (S, M, L, XL) is not standardized across manufacturers. A size Large with a 20" body width from one mill can be a 22" body width from another — both will say "Large" on the tag. For blank tees specifically, this matters more than for branded fashion, because:
- You're usually buying in bulk, so a sizing mismatch multiplies across dozens or hundreds of units.
- Decoration (screen printing, DTG, embroidery) is positioned based on exact garment dimensions — a shirt that runs narrower throws off your print placement.
- Reorders happen months apart; if you only remember "I bought a Large," you may not get the same fit twice unless you're buying the same block.
The fix is to stop relying on the letter and start relying on the tape measure.
How to Measure a T-Shirt (Garment Measurements, Not Body Measurements)
Lay the shirt flat on a table, front side up, and smooth out any wrinkles. Measure with a soft tape measure, not a ruler.
Chest / Body Width
Measure straight across from armpit seam to armpit seam. Double this number for the full circumference — a flat measurement of 20" means a 40" chest circumference.
Body Length
Measure from the highest point of the shoulder seam (where it meets the collar) straight down to the bottom hem.
Shoulder Width
Measure from the end of one shoulder seam to the end of the other, straight across the back.
Sleeve Length
From the shoulder seam to the end of the sleeve hem.
Blank Mind Pima Cotton Tee — Reference Measurements
These are the flat garment measurements for our classic-fit Pima cotton crewneck, the block most of our screen printers and clothing brands build around:
| Size | Chest (flat, in) | Body Length (in) | Shoulder Width (in) | Sleeve Length (in) |
|---|---|---|---|---|
| S | 18.0 | 27.0 | 16.5 | 7.5 |
| M | 19.5 | 28.0 | 17.5 | 8.0 |
| L | 21.0 | 29.0 | 18.5 | 8.5 |
| XL | 22.5 | 30.0 | 19.5 | 9.0 |
| 2XL | 24.0 | 31.0 | 20.5 | 9.5 |
For a looser silhouette, our oversized blank tees add roughly 2-3" of chest width and 1-2" of body length at the same labeled size, while the relaxed fit line sits between classic and oversized. If you're deciding between those three silhouettes first, our fit comparison guide breaks down exactly how each one drapes.
Why Pima Cotton Measurements Hold Up Over Time
Garment measurements are only useful if they stay accurate after washing. This is one of the practical advantages of Peruvian Pima cotton over standard upland cotton: its longer staple fiber produces a tighter, more stable knit that resists the shrinkage and distortion that shorter-staple cotton is prone to. A Pima tee measured fresh out of the bag should measure within a quarter inch of the same spot after a dozen washes, assuming it's laundered correctly. Fabric weight plays into this too — if you want the engineering side of why heavier GSM fabrics hold shape better for printing, see our GSM weight guide.
Matching Size to Use Case
| Use Case | Recommended Fit | Why |
|---|---|---|
| Screen printing / brand launch | Classic | Predictable chest width keeps print placement consistent across a run |
| Streetwear / drop culture | Oversized | Boxier shoulder and longer body length suit graphic-heavy front prints |
| Everyday retail basics | Relaxed | Extra room without losing shape structure |
| Team or event apparel | Classic | Easiest to size a roster against standard charts |
Common Measuring Mistakes
- Measuring a worn or stretched sample. A shirt that's already been worn several times without washing can read up to half an inch wider at the chest.
- Confusing body measurements with garment measurements. A size chart listing "40 inch chest" usually means the person's body, not the flat garment — always confirm which the chart is showing.
- Ignoring shrinkage allowance. Ask your supplier whether listed measurements are pre-wash or post-wash; for Pima cotton the difference should be minimal, but it's worth confirming before cutting print files to exact dimensions.
FAQ
Do Blank Mind sizes run true to standard US sizing?
Our classic fit is built close to standard US unisex sizing, but we recommend checking the chart above rather than assuming — especially if you're used to a different supplier's block.
Will my shirt shrink after washing?
Expect minimal shrinkage (under 3%) when washed cold and tumble dried low. See our care guide for the full wash process that keeps measurements stable.
How do I size a bulk order across a team with mixed body types?
Use the garment chest measurement (not body chest) and add roughly 4-6 inches of ease over the wearer's actual chest circumference for a comfortable, non-clingy classic fit.
What if I need a size outside this chart?
