What the Dress Size Calculator does
Dress Size Calculator: calculates Approx. US Size and Note from Bust, Waist and Hip. Example: bust 90 cm, waist 70 cm and hip 95 cm gives approx. US size 8.
Enter Bust, Waist and Hip and the Dress Size Calculator reports Approx. US Size and Note. Results refresh instantly, so trying variations costs nothing but a moment.
Context matters more than the number itself. Age, build and activity all shift it. That is usually what brings people tracking a goal here.
There is no account, no upload and no server round trip, because the page does the work itself.
The meaning of each field, the formula in use, and a worked example that starts from the default inputs are all further down.
What do the Dress Size Calculator fields mean?
The Dress Size Calculator uses 3 inputs. A complete set of starting values is loaded for you, so nothing is required before the first result appears.
| Field | What to enter | Default |
|---|---|---|
| Bust | measured in cm; accepts 60 to 150 | 90 |
| Waist | measured in cm; accepts 50 to 140 | 70 |
| Hip | measured in cm; accepts 60 to 160 | 95 |
How does the Dress Size Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
Validation is deliberately strict: silently coercing a bad value is how wrong numbers get trusted.
Worked example
These are the values the Dress Size Calculator loads by default, and the result it produces from them. This walkthrough uses the starting values, which means you can follow along without typing anything.
| Bust | 90 cm |
|---|---|
| Waist | 70 cm |
| Hip | 95 cm |
| Approx. US Size | 8 |
|---|---|
| Note | Rough US dress size ≈ 8 from bust/hip. Always check the brand’s size chart. |
How to use it
- Enter Bust in cm (60 to 150).
- Set Waist in cm (50 to 140).
- Put Hip in cm (60 to 160).
- Because it recalculates as you type, you can dial a value in rather than guessing and re-running.
- You get Approx. US Size and Note back.
- Share the link rather than a screenshot. It carries the values with it.
What this tool does not do
- Body composition, ethnicity and age all shift what a "normal" result means.
- These formulas come from population averages and cannot account for your medical history.
- There is no audit trail: if you need one, record the inputs alongside the output.
- It validates ranges, not intent. A value can be accepted and still be the wrong one to use.
Frequently asked questions
Enter Bust in cm, Waist in cm and Hip in cm. Look for the unit beside each label; the result is reported in a stated unit as well.
Bust accepts 60 to 150 cm. Out-of-range entries are refused up front, which is safer than silently clamping them.
With the values loaded when the page opens, approx. US size comes out as 8. Change a value and the number is recomputed on the spot.
Nothing is stored. The page has no back end to send data to, and holds your input only in memory.
It is free to use, with no premium tier holding back the useful parts.
The arithmetic is correct; the model is a population approximation. Individual factors move the real answer, so treat the figure as context rather than a conclusion.
