How to measure shirt hem width: five clear checks

A bottom-width number needs a route, not just a label.

By The Five Edit editorial team · Published 03 November 2026 · 5 min read

Measure shirt hem width straight across the lower opening, using the endpoints required by the maker's guide. For the curved-hem method described here, those points are where the side seams meet the hem. Keep the garment flat and relaxed, then record the route, fastening state and unit beside your number.

1. Does the listing mean bottom width or length?

Bottom width runs across the shirt. A length measurement follows a separately named vertical route. Clarify the field before taking a number: the word hem can refer to the finished edge without explaining which dimension the seller wants.

Proper Cloth describes bottom width at the bottom of the side seams. That is a finished-garment record, rather than a tape placed around your hips. Keep the source's label and method together.

If a resale listing says “hem length” beside a horizontal photograph, ask which record the seller intends. You can resolve the wording before deciding whether the two shirts are comparable.

2. How should the shirt lie on the surface?

Follow the requested fastening and preparation method. The VIKTR MARTIN guide uses a flat surface, a naturally fastened garment and folds smoothed without stretching. Record the same condition when requesting a second measurement.

Look underneath as well as at the visible front. A folded layer can make a photograph difficult to interpret. Smooth it gently rather than pulling the sides apart to make the tape reach a preferred number.

For example, keep “buttoned, relaxed, front facing up” as a description beside the value. If the garment has a different closure or cannot lie flat in that position, name the difference and ask for the appropriate method. The aim is a repeatable observation, not forcing every design into the same outline.

3. Where do the endpoints go on a curved hem?

For the curved-shirt method in the VIKTR MARTIN guide, use the points where the side seams meet the hem and measure straight across. Following the rounded lower edge describes a different route. A longer curve is not a wider flat opening.

The Monks of Method hem guide makes the same straight-route distinction. Its rounding and ordering instructions belong to its own service; retain the precision requested by the maker or listing you are using.

Side splits, asymmetric fronts or a shape that does not match the illustrated method deserve a specific question. Ask which corners or seam junctions the seller used. Keep that uncertainty in the record until both sides of the comparison refer to the same points.

4. Which details should travel with the number?

Record the route, endpoints, fastening state, relaxed or stretched condition, and unit. A labeled photograph can show where the tape starts and ends. It is more informative than supplying extra decimal places without a method.

Keep an original listing value visible when asking for clarification. For instance, write “seller's bottom width, method not yet confirmed” rather than relabelling it as a body size. There is no need to convert an unexplained width into a circumference.

Hemdwerk's hem-shape explanation distinguishes straight and rounded cuts. Shape can explain why two outlines look different, but it does not complete a missing measurement route. Our flat clothing comparison guide provides a broader record for other dimensions.

5. How do you compare two hem-width records?

Compare matching methods on similar garments first. A bottom-width record can support that comparison while leaving the chest, length, movement and intended silhouette as separate questions.

Use the wearing and design ease guide when the question is about room or shape rather than a flat route. Keep the cuff-width method in its own field too; a sleeve opening and a shirt's lower opening describe different parts.

For used clothing, our thrift inspection checklist also covers condition. Ask about an altered hem or a changed side split before treating an old size label as the whole description. A clear record makes the conversation more useful; it does not promise a particular fit or alteration.

Frequently asked questions

How do you measure shirt hem width?

Use the maker's named straight route across the lower opening. Keep both endpoints, the fastening state, fabric condition and unit with the result.

Should I follow the curve of a rounded hem?

Not for the flat-width method described here. Its endpoints are the side-seam/hem junctions, joined by a straight route across the shirt.

Is hem width the same as shirt length?

They describe different directions. Confirm the requested field when a listing uses hem length beside a horizontal photograph.

Should I double a flat hem-width number?

Keep the value in the field and method requested. An unexplained doubled value does not establish body circumference, ease or fit.

What if the shirt has side splits?

Ask for the maker's or seller's exact endpoints. Do not assume that the lowest front, lowest back and top of a split are interchangeable.

Can the diagrams tell me which size to buy?

They explain conceptual routes and questions. They are not scaled patterns, measurements of your shirt or a size recommendation.
