Comfort Colors C4017 size chart

Every published size in the C4017 run, set against the styles printers cross-shop it with — and the stated tolerance that decides how much the differences are worth.

Last verified: 26 August 2026

A Comfort Colors C4017 publishes a 20.5" chest and a 29.5" body length at Medium, laid flat — half an inch wider and half an inch longer than a Gildan G500 at the same letter. That half inch of width holds at every size from S to 3XL. This Comfort Colors C4017 size chart prints the full published run with the per-size deltas.

One number to settle first: a C4017 Medium is 20.5" across, not 22.0". In these specs 22.0" is a Large in six of the eight styles, and the C4017 Large is 22.5". The claim that a Comfort Colors Medium runs two inches wider than a Gildan Medium does not survive the published sheets. The gap is half an inch.

The Comfort Colors C4017 size chart, S to 3XL

Six published sizes. The step columns give the difference from the size below.

SizeChest (in)Length (in)Chest stepLength step
S18.528.0
M20.529.5+2.0+1.5
L22.530.75+2.0+1.25
XL24.532.0+2.0+1.25
2XL26.533.0+2.0+1.0
3XL28.534.0+2.0+1.0

Chest grades in flat 2.0" steps, like every other unisex style here. Length does not: it front-loads, adding 1.5" from S to M and 1.25" through L and XL — the only quarter inch in the set — before settling to 1.0" at the top. That front-loading is why the length advantage disappears at the big sizes.

How it compares at shared sizes

Two columns cover three styles: the Gildan G500 and Bella+Canvas 3001C publish an identical grid at every shared size, and the Hanes 5250T grades length differently at the top. Positive means the C4017 is wider or longer.

Width is dull: +0.5" against all three at every size. Not the widest everywhere, though: the Next Level 3600 publishes 19.0" at S against 18.5", and ties at M. Only from L up does the C4017 hold the widest unisex chest alone.

Length carries the shape story. Through XL the C4017 is the longest style in the set and its lead grows: 0.5", 0.75", then a full inch. Then it stops. From XL to 2XL the Hanes adds 2.0" of length against the C4017's 1.0" and catches it exactly at 33.0"; at 3XL both sit at 34.0", as does the Champion T525C. At the top of the run, then, this shirt is wider than everything and no longer than the longest — width without length, the proportion people call boxy. Full ranking: which blank runs biggest.

The tolerance is bigger than the difference

Comfort Colors states a manufacturing variance of ±0.8" on the C4017; the other seven blank styles in the catalog state ±0.3". That is the most useful fact on this page, because it is larger than every delta in the table above.

A Medium specified at 20.5" can arrive anywhere from 19.7" to 21.3". A G500 Medium at 20.0" ±0.3" lands between 19.7" and 20.3" — the narrowest legitimate C4017 is exactly as wide as the narrowest legitimate G500. On one shirt the half-inch difference is not something to count on; across a run of a few hundred it is a real average.

What else the catalog row holds

The point-of-measure set for tops has eight entries; this row carries all eight. Sweep is the one that explains the silhouette: the hem runs about an inch wider than the chest at every size, where the G500's hem sits about half an inch narrower. The C4017 flares; the Gildan tapers.

The hem is drawn wider than the chest, matching the specification. Sleeve length is not drawn, because the catalog's sleeve figure is not specific to this style.

What the catalog does not hold

The row records the C4017 as garment-dyed — dyed after assembly rather than at the yarn stage — and the source listing calls it ringspun garment-dyed. That is all this data says about the fabric.

It carries 180 gsm and a knit construction, but so do all fifty-three blank spec rows: a file default, not a published Comfort Colors weight, so no ounce figure appears here. Composition is blank, and there is no shrinkage or colour-by-colour data — which matters more on a garment-dyed style than a piece-dyed one. The catalog offers no reason for the wider tolerance.

Where these numbers came from

The specification traces to a2zclothing's C4017 listing, the source recorded in the catalog row. Check the brand's current sheet before a large order — blank specs get revised.

If you own a tee that already fits, measure it and shop its number instead of its letter: the measuring guide, pit to pit, and vanity sizing on why the tag never carried it. All eight styles side by side: the t-shirt size chart. The other per-style pages: the blank tee shelf.

Common questions

Does the Comfort Colors C4017 run big or small?
Bigger than the other unisex blanks here, but by less than its reputation suggests: 0.5" more chest than the Gildan G500, Bella+Canvas 3001C and Hanes 5250T at every size S to 3XL, and 0.5" to 1.0" more length from M through XL. At 2XL and 3XL the Hanes and the Champion T525C match its length exactly, at 33.0" and 34.0". Its stated variance, ±0.8", is larger than the chest difference itself.
What is the chest measurement of a Comfort Colors C4017 in Medium?
20.5" across, laid flat, pit to pit one inch below the armholes — half an inch over a Gildan G500, Bella+Canvas 3001C or Hanes 5250T Medium (all 20.0"), and identical to a Next Level 3600 Medium. It is not 22.0": in these specs 22.0" is a Large in six of the eight styles, and the C4017 Large is 22.5".
Is the Comfort Colors C4017 unisex?
Yes. The catalog records it as a unisex cut, and the run behaves like one — a straight block graded in even 2.0" chest steps from S to 3XL. For scale, the one women's cut in the same data, the Gildan G500L, publishes 17.5" at Medium against 20.5": three inches of flat width on the same letter.
