To find your men's t-shirt size online, two measurements are sufficient: chest circumference and back length. These two indicators, combined with the manufacturer's size guide, help avoid most ordering errors. The rest depends on the desired fit — tailored or looser — and the fabric material, which influences the final look.
Why sizes vary from one brand to another
An M from one brand might correspond to an L from another. The reasons are simple: each brand defines its own sizing charts based on its target customer, country of origin, and the cut it aims for. A t-shirt designed for an athletic build will not have the same measurements as a straight-cut or relaxed-fit model.
That's why you should never assume your size: you need to measure it, then compare it to the seller's size guide.
The two essential measurements
Chest circumference
This is the main measurement for a t-shirt. Wrap a tape measure flat around the widest part of your chest, under your arms, keeping your arms slightly away from your body. Note the value in centimeters.
Back length
Measure from the top of your neck (at the base of the collar) to the desired waistline. This measurement prevents t-shirts from being too short, exposing your back when you raise your arms, or too long, falling over your hips if that's not the desired effect.
Shoulder width (optional but useful)
For tailored fits, it's useful to check shoulder width: measure from one shoulder point to the other across your back. A t-shirt with shoulder seams that extend beyond your shoulders immediately gives the impression of a poorly chosen size.
How to read a size guide
Size guides generally provide centimeter ranges for each size (S, M, L, XL…). If your measurements fall between two sizes, several criteria guide your choice:
- Desired tailored fit: go up a size if you have broad shoulders, down a size if your chest circumference is at the lower end of the range.
- Fabric with little elasticity (linen, woven cotton): opt for the larger size if in doubt, as the fabric will not adapt.
- Cotton jersey with some stretch: the indicated size is usually sufficient.
Tailored fit vs. regular fit: what's the difference in size?
| Fit | Characteristic | Sizing advice |
|---|---|---|
| Tailored (slim) | Follows body shape, tapered at the waist | Take your usual size if you are in the average range |
| Regular (straight) | Falls straight without following the torso | Your standard size is suitable in most cases |
| Loose (relaxed/oversized) | Intentional volume, dropped shoulders | Stick to your usual size — do not go down a size, as this changes the intended proportion |
Material and shrinkage: an often-overlooked factor
Cotton, especially unwashed jersey, can shrink during the first wash. Before ordering, check if the t-shirt has undergone Sanforization or pre-washing. If not, it may be wise to go up a size if you wash at high temperatures.
Linen, on the other hand, tends to relax slightly with time and wear. It becomes softer with each wash but rarely loses significant length.

Online ordering: the right reflexes before validating
- Take your current measurements — your body changes, old measurements may no longer be accurate.
- Consult the product-specific size guide, not a generic chart.
- Read customer reviews: if they unanimously mention that the t-shirt runs large or small, take that into account.
- Check the return or exchange policy before validating, especially for a first order.
If you are still unsure, browsing the product descriptions of the men's t-shirts in the collection can help: each model indicates the cut and exact flat garment measurements, which remains the most reliable reference.
Frequently asked questions
I'm between two sizes: what should I choose?
It depends on the desired effect. If you want a neat, tailored fit, take the smaller size provided your shoulders fit within the range. If you prefer ease of movement or wear the t-shirt over another piece, opt for the larger size.
Are international sizes (S, M, L) standardized?
No. The letters S, M, L, XL do not have a universal definition. They vary by brand, country, and cut. Only the seller's size guide in centimeters is authoritative.
Can a t-shirt shrink after washing?
Yes, it's possible, especially with untreated cottons washed at high temperatures. To limit this risk, wash at 30°C and prefer flat drying or air drying. The care instructions on the label remain the most reliable reference.
