The MAXCT half-turtleneck knitted sweater comes in White or Black and sizes M, L and XL. Its listed chest changes by only 3 cm between neighboring sizes, while the source warns that flat manual measurements can differ by 1–3 cm. That makes a single chest number a weak tie-breaker. Compare four dimensions with a knit you already like, and clarify the measurement route before treating a near match as exact.

Put all four chart rows beside your reference knit

These are the numbers published for this particular sweater, in centimeters. “Back center length” is the source label; it does not explain its start and end points.

Lay your reference sweater flat without stretching it. Record its chest, shoulder, sleeve and center-back length using the same endpoints as the seller’s chart. The product page does not explicitly say whether “chest” means a full circumference or a flat width doubled, so confirm that method if it changes your choice. A body chest measurement is a different kind of number; it needs the ease you prefer before it can be compared with a garment.

Work through a close call

Suppose a sweater you wear comfortably measures 96 cm at the chest, 39 cm at the shoulder, 64 cm at the sleeve and 66 cm down the center back, using the same routes as this chart. L is closest overall: its listed values differ by 1, 0, 0 and 1 cm. M is 4 cm smaller at the chest but only 1 cm different at the shoulder, sleeve and length. XL adds 2 cm to the reference chest and 3 cm to the back length. This is a comparison exercise, not a promise that L will fit you: the source’s 1–3 cm manual measurement allowance is as large as each adjacent chest step. If a centimeter changes whether you can wear an undershirt, ask for a measured sample or choose based on the fit detail you can verify.

Decide what the collar and jacket need to do

The gallery shows a plain high neck with no visible zip or buttons, plus a white and a black version. For a lighter contrast under a dark jacket, inspect the White photos; for a lower-contrast neckline, inspect Black. Those are styling choices, not a claim about warmth or opacity. Check your jacket’s shoulder and sleeve room against the sweater you measured, especially if you plan to add another layer.

The listing gives a model note of 172 cm, 56 kg in M, but no model chest or preferred ease. It also gives the fiber mix as 87% acrylic, 10% polyester and 3% spandex, without a measured stretch range, collar opening or wash-shrinkage result. Use the live product page for the current choices and full source chart; resolve those missing details if they matter more to you than a close numerical match.
