How to Read a T-Shirt Size Chart if You Are Between Sizes

Being between sizes is not the problem. Not knowing what the numbers mean is. Vee explains the two measurements that actually matter and how to make the right call every time.

When your chest measurement falls between two sizes, the answer is not always to size up. It depends on the cut and the intended fit. For oversized graphic tees, size up — the print needs room and the silhouette is designed for drape. For regular or fitted cuts, size down — structure is the point and extra fabric removes it.

🛑 VEE'S RULE: IGNORE THE LETTER. USE THE NUMBER.

S, M, L are internal labels that mean different things at every brand. The flat lay chest measurement in inches is the only number that is consistent. If a brand publishes measurements, use them. If they only list S/M/L with no numbers, that is a red flag about how much they care about accurate fit.

What "Between Sizes" Actually Means

Your chest measures 22 inches — the flat lay half-circumference. On Brand A's chart, 22 inches puts you at the top of their M range. On Brand B's chart, 22 inches is the entry point for their L. Neither chart is wrong. They just have different blocks.

Being between sizes is not unusual. Most people fall at the boundary of two adjacent sizes. The question is not which size fits — it is what fit you are trying to achieve.

The Two Measurements That Matter

Shoulder measurements, sleeve lengths, neck circumference — these are secondary for a graphic tee. Two measurements determine 95% of fit outcomes:

Chest width (flat lay): Measure the front panel from seam to seam, lying flat. This is the number brands publish on their charts. If your body measurement is 44 inches around the chest, your flat lay is 22 inches — divide by 2.

Body length: From the top of the collar (nape of neck) straight down to the hem. Determines whether the tee hits at the hip, waist, or below — which drives the entire silhouette.

Compare both numbers to the brand's chart before buying. If the brand does not publish both, use their chest width at minimum and make a judgment on length from the size range they state.

Drop Shoulder and Oversized Cuts: The Exception

On a drop shoulder or oversized-cut tee, shoulder measurements are irrelevant. The seam is intentionally displaced off your natural shoulder by 1–3 inches as part of the design. Do not size up to "get the shoulder right" on an oversized tee — the seam is supposed to be where it is.

For these cuts, chest width and body length are all that matters. The shoulder handles itself.

When to Size Down from Your Border Measurement

The one scenario where sizing down is clearly correct: you want a neat, structured look and the tee is a regular-fit cut. A tee that fits accurately at the chest sits clean — no excess fabric at the sides, no lateral billowing, no bunching. Going up one size on a regular fit because you are "between" adds unintended excess that the cut was not designed to carry.

For graphic tees with significant print areas, however, a tee that is slightly tight across the chest pulls the fabric horizontally — distorting the design. Sizing up removes that tension. The print reads cleanly. This is the correct call for any tee where the design is the primary purpose.

What to Do When There Is No Size Chart

Do not buy.

A brand that does not publish measurements is either indifferent to returns or indifferent to fit — both are the same problem. At ₹799 or above, the brand has the information. They have chosen not to share it. That choice tells you something about how they operate.

The size letter is a convention. The chest width in inches is a fact. Always buy from the fact.

/// Between Sizes — Size up or size down? The decision matrix.

Situation	Decision	Why
Graphic tee, oversized cut	Size up	Print needs room — a tight fit distorts the design and reads as too small
Graphic tee, regular cut	Size down	Clean structure is the point — the tee should sit correctly, not fill out
Hoodie, streetwear oversized	Size up	Extra fabric adds drape and silhouette — the loose cut is intentional
Fitted base layer	Size down	Should hug the body — sizing up makes it look shapeless under layers
You want body length priority	Size up	Go larger if tee length matters more than chest width to you
Chest width is borderline	Check flat lay	Look at actual measurement, not the letter — M at one brand is L at another

QWhat does it mean to be between sizes and how do you know?

Your body measurements fall in the overlap between two adjacent size ranges. For example, your chest measures 22 inches — which is the top of an M and the bottom of an L on most Indian brand charts. Neither size is technically wrong. The question is what fit you want, not what size you are.

QShould you size up or down if you are between sizes for a graphic tee?

Size up for oversized and graphic tees. The visual impact of the design needs room — a tee that pulls slightly across the chest distorts the print and reads as too small. Size down only when you want the tee to read neat and structured, not when the design is the centrepiece.

QWhat measurements actually matter when buying a t-shirt online in India?

Two: chest width (across the front panel from seam to seam, flat lay measurement) and length (nape of collar to hem). Ignore shoulder measurement unless you are buying a regular fit where shoulder seam placement matters. For oversized and drop-shoulder cuts, those seams are intentionally displaced anyway.

QCan you trust brand size charts, or do they just list generic numbers?

It varies. Premium streetwear brands in India tend to publish accurate flat-lay measurements from actual garments. Fast fashion brands often reuse generic charts that do not match their actual production. When in doubt, look for brands that publish actual garment measurements — not just S/M/L labels.

QWhat do you do if a brand has no size chart?

Do not buy. A brand that does not publish measurements either does not take fit seriously or does not want you returning things. Neither is acceptable for ₹799 or above. If you cannot verify the chest width before purchase, you are gambling with the fit.

A size chart is a tool. Use the numbers. Ignore the letters.
