True to size, runs small, runs large: what they mean
What does true to size mean? It means a garment matches the brand’s own size chart. What runs small and runs large say, and why neither tells you about your shape.
InspirationThe plain meaning
“True to size” means a garment matches the size it is labelled as: if you normally wear that size from this brand, or your measurements match the brand’s chart, it should fit as expected. “Runs small” means it comes up smaller than its label, so shoppers suggest choosing the next size up. “Runs large” means the opposite, and a size down is suggested.
These phrases appear on listings and in shoppers’ comments. They are useful as a nudge, but they are measured against something quite narrow.
What they are measured against
When a brand says an item is true to size, it means the finished garment matches its own size chart. When a shopper says it, they usually mean it matched the size they normally buy, from this brand or from others. Those are two different yardsticks.
Sizes are not fixed across the industry. A UK 12 in one brand can be noticeably roomier than a UK 12 in another, and sizes differ between countries too. Our article on UK, EU and US dress sizes shows how those systems compare, and brand size charts versus made to measure looks at Pakistani charts in particular.
Why the phrase says nothing about your shape
A size is a set of measurements for an imagined body with fixed proportions. If your bust, waist and hips do not fall in the same size row, or you are taller or shorter than the chart assumes, a garment can be true to size and still not fit you.
- Proportions. Someone with narrow shoulders and fuller hips may find a dress tight at the hip and loose at the shoulder in the same size.
- Height. Lengths are graded for an average height; true to size does not mean the right length for you.
- Fabric. Stretch knits forgive a lot; crisp cotton forgives nothing. A review of a stretch top does not carry over to a woven one.
- Intended fit. An oversized or relaxed style is meant to be roomy. “Runs large” may just be a shopper describing the design.
Reading the phrases sensibly
Treat “runs small” or “runs large” as a hint about direction, then check the numbers. Look for the garment’s own measurements, not just body measurements, and compare them with a similar piece you own that fits you well. The guide to measuring clothes that fit you explains how. The difference between body and garment figures is set out in body versus garment measurements.
If comments disagree, look for shoppers who mention their height and measurements; their experience is easier to compare with your own.
Made to measure takes the guesswork out
When a garment is cut from your own measurements, the question of whether it runs small or large disappears. You give your bust, waist, hips, lengths and preferred ease, and the garment is cut to those numbers. Our quote form also accepts a standard UK size as a starting point, and we confirm the key measurements with you before cutting.
Use the size guide to take your measurements, then send them through the quote form. Custom stitching explains the rest, and everything is agreed in your written quote first.
Common questions
If something runs small, should I size up?
Often, but check the garment measurements first. If only the bust is tight and everything else is right, sizing up may make the shoulders and length too big.
Does true to size mean the same in every country?
No. It only means the item matches that brand’s chart, and size labels differ between brands and between the UK, the US and Europe.
Why does the same size fit differently in two colours?
Different fabrics or production runs can behave differently, and darker or heavier fabrics may be cut from a separate batch. Measuring the garment is the reliable check.
