Size recommendations
Know your size before you order.
Dress Measurement matches your body measurements to the size charts of 122 brands and gives you a confidence-rated recommendation. Free for every user, no subscription needed.
What size am I in this brand?
Dress Measurement compares your saved measurements against the brand's published size chart and returns a recommendation in seconds, for brands like H&M, Zara, Uniqlo, and Lululemon. Enter your measurements once in the app; every brand recommendation uses the same profile. There is no need to look up individual brand charts, convert units, or guess which size spans your proportions.
The recommendation covers tops, bottoms, dresses, activewear, and suits (including women's suits) where the brand's size chart includes the relevant measurement ranges. Categories not covered by a brand's chart are not shown.
The size card also shows your size in US, UK, EU, Japanese, Australian and New Zealand, and Korean numbering. Each region is scored against its own body-measurement chart, so every region's size comes from a chart built for that region rather than from adding a number to another region's size. You choose your sizing region when you set up the app, in App Settings, or on the Sizes screen. Where a brand's chart uses a different system from yours, its sizes are labelled to match, for example "UK 12" or "US 8".
How confidence levels work
Every recommendation comes with a confidence level that tells you how cleanly your measurements fit into one size. Confidence reflects measurement alignment, not brand quality. A high-confidence result means the algorithm found a clear match; a low-confidence result means at least one measurement sits outside the expected range for any single size. If you have set a fit preference (slim or relaxed) on your profile, the app may adjust your size up or down and mark the result as "Preferred fit."
Shown when you have set a fit preference in your profile. Dress Measurement nudged the size up or down because your measurements land at the edge of the range and the adjacent size still matches cleanly.
All relevant measurements fall clearly within one size range. Strong alignment across bust, waist, hip, or chest measurements.
Most measurements point to one size, but one sits near a size boundary. The recommendation is still valid; check the borderline measurement before ordering.
Measurements span more than one size range. The algorithm returns a best-fit result, but you should verify directly against the brand's chart or consider size-up for comfort fit.
Free for every user on every tier
Size recommendations are not a paid feature. Every Dress Measurement user, including those on the Free tier, can check their size in any supported brand at any time. This is deliberate: helping you find the right size is the core value of the app, and putting it behind a paywall would undermine that.
The Tailor Shop subscription unlocks unlimited profiles, custom measurements, photos, notes, and CSV export. It does not gate size recommendations.

Requesting a new brand
We add brands when there is sufficient demand for a given label. If your preferred brand is not in the app, search for it and tap Request a Brand (or "Can't find your brand? Request it"), then send the brand name and, if you know it, the brand's website. If you cannot use the app, email us with a request instead. A link to the brand's measurement-based size chart helps if you have one. Brands that publish detailed numeric size charts (with bust, waist, hip measurements rather than S/M/L only) are added fastest.
