No guesswork. No returns you could've avoided. Just the numbers.
Sizing on printed apparel isn't like buying a shirt off a rail — you can't try it on first, so we've made sure the actual measurements are on every product page. This guide tells you how to use them.
How to measure yourself
Grab a tape measure and measure yourself directly — not a shirt you already own, since fit varies between brands and styles.
- Chest: Measure around the fullest part of your chest, under your arms, keeping the tape level.
- Body length: Measure from the highest point of the shoulder (next to the neck) straight down to where you want the hem to sit.
- Sleeve length: Measure from the centre back of the neck, across the shoulder, and down to the end of the sleeve.
Compare your measurements to the garment measurements on the product page — not to your usual "size" in a shop, since a Blockrat Large and a high-street Large aren't guaranteed to match.
A note for our US customers
Our garments run slightly smaller than typical US sizing. If you're ordering from the United States, we'd generally suggest going up one size from what you'd normally wear. Every product page also carries this note where relevant.
Fit types across the range
- Unisex tees: Medium, true-to-size fit — not boxy, not fitted. Built to be worn, not modelled.
- Women's fits: Cut with a more tailored silhouette — check the specific garment measurements on each women's product, as these differ from the unisex block.
- Hoodies & sweatshirts: [Fit description to confirm — relaxed/oversized/regular?]
- Headwear: [One-size-fits-most / adjustable — confirm exact spec]
Exact measurements
Every product page carries a size chart specific to that garment, in centimetres — chest width, body length, and sleeve length by size. Always check the chart on the exact product you're buying rather than assuming sizes are identical across styles, since cut varies between our T-shirts, hoodies, and women's fits.
T-Shirts (Unisex Organic Cotton)
| Size | Body Length (cm) | Chest Width (cm) | Sleeve Length (cm) |
|---|---|---|---|
| S | 69 | 49.5 | 22.5 |
| M | 73 | 53.5 | 24 |
| L | 75 | 56.5 | 24.5 |
| XL | 77 | 59.5 | 25 |
| 2XL | 79 | 63.5 | 25.5 |
Regular, true-to-size fit. Chest width is measured flat, so double it for the full circumference (e.g. size M = 107 cm chest circumference).
Hoodies (Unisex Heavy Blend)
| Size | Length (cm) | Width (cm) |
|---|---|---|
| S | 69 | 51 |
| M | 71 | 56 |
| L | 74 | 61 |
| XL | 76 | 66 |
| 2XL | 79 | 71 |
| 3XL | 81 | 76 |
| 4XL | 84 | 81 |
| 5XL | 86 | 86 |
Relaxed, true-to-size fit with roomy sleeves and a drop-shoulder cut — this is a looser fit than the T-shirts by design, not a sizing error. Width is measured flat across the chest, so double it for full circumference.
Headwear
One-size-adjustable is standard for our caps.
Between two sizes?
Go with the size closer to your usual fit if the garment is described as true-to-size (T-shirts). Go with the size up if you prefer things roomier, especially on the hoodie's drop-shoulder cut.
