Grading Wool Coats for Fall 2026: Weight and Lining Beat the Label

November 4, 2026

Grade the cloth, then the coat

Our grading starts with a number most listings hide: cloth weight. As a working grid, coating cloth over about 400 grams per square metre is a true heavy winter coat, 350 to 400 is medium-heavy, 300 to 350 is medium, and under 300 is a mid-season coat wearing winter styling. That single fact predicts warmth better than any percentage on the label, because a thin 100 percent wool coat can be colder than a heavier blend with less wool in it.

One trap: brands quote weight per linear metre as often as per square metre, and the linear figure looks bigger because coating cloth is woven wide. If a weight sounds huge, it is probably linear. Divide by roughly 1.5 for a working square-metre estimate.

The label check, done properly

The composition label is the one claim on a coat that labelling law actually guarantees, at least in regulated markets: fibre names and percentages by weight, largest first. Grade it accordingly. A coat that states its split plainly, including recycled wool content where it exists, starts ahead of one hiding behind the words wool blend with no percentages at all.

Fineness is the second label fact worth having. Fibre diameter is measured in microns, and finer fibre feels softer against the neck and wrist, which is where a coat is actually felt. Coarse cloth in a beautiful cut still loses the grade if it is unpleasant at the collar by the second wearing.

Construction: the five-minute version

Shoulder first. The seam should end at your shoulder bone with a layer underneath, and the collar should lie against the back of the neck. A coat that gapes or pulls in the shop does not improve at home. Then the lining: look for a full lining cut with a little ease, often a centre-back pleat, stitched cleanly at hem and cuffs, that does not drag on the outer cloth when you reach forward.

Buttons and seams finish the check. Buttons should be sewn through with thread that matches the load they carry, and seams should sit flat without puckering. None of this requires expertise, just the willingness to turn the coat inside out before paying for it. The inside is where the grade is decided.

This season's grades, in one line each

Applying the grid to the fall crop: heavyweight single-breasted coats in stated 400-plus cloth with full linings grade highest, because they are honest winter coats. Mid-weight fashion coats in the 300 to 350 band grade well as mid-season pieces and poorly when marketed as deep-winter warmth, and that marketing gap, not the coat, is what loses the marks. Unlined or half-lined styles in thin cloth grade lowest for fall, whatever the label percentage says.

Buy the weight your winter actually is. A 450 gram coat in a mild climate is its own kind of mistake, just a warmer one.

Frequently asked questions

How heavy should a winter wool coat be?

For real winter warmth, look for cloth over about 400 grams per square metre. Between 350 and 400 is medium-heavy, 300 to 350 is medium, and under 300 is best treated as a mid-season coat regardless of how it is styled.

Is 100 percent wool always better than a blend?

No. Weight matters as much as content: a heavier blend can be warmer and harder-wearing than a thin pure wool coat. Read the stated percentages and the cloth weight together, and be suspicious when neither is given.

What should I check in a coat lining?

That it is full, cut with some ease such as a centre-back pleat, and stitched neatly at the hem and cuffs without pulling when you reach forward. A lining that drags or twists signals construction that will not hold up.

Why do coat weights sometimes look suspiciously high?

Brands often quote grams per linear metre rather than per square metre, and a linear metre of wide coating cloth weighs much more. As a rough conversion, divide the linear figure by about 1.5.
