How to Measure for a Dress Size
- Bust, tape around the fullest part, level and snug, not tight. Wear the bra you plan to wear with the dress, or a light, non padded bra.
- Waist, your natural waist above the navel, where you bend.
- Hips, fullest part of hips and seat.
- Toggle cm or in. If results look wild, flip the unit and try again.
- No tape, use a string, mark it, measure the string against a ruler.

Why you can trust this, and what it cannot do yet
Why this works
I mapped common ready to wear size charts across US, UK, EU, then tuned for typical ease ranges in dresses. The calculator picks the closest baseline size, then shows regional equivalents so you can shop without guesswork.
Limits
This does not account for brand specific blocks, petite or tall scaling, or knit versus woven stretch adjustments. Use your result as a starting size, then read the product chart if the brand provides one.
If you’re between sizes
- For most dresses, start with bust.
- For corseted or tailored styles, waist can matter more.
- If hips run larger, look for A line cuts or fabric with stretch.
- When unsure, choose the larger size, then tailor for a clean fit.
Mid body next steps
- Convert other items, shop tops, jeans, and shoes with one map, open the International Size Converter.
- Dial base fit, fewer returns start here, find your bra size.
Dress length by height, quick guide
- Mini, mid thigh for most, consider tights or shorts if you move a lot.
- Knee length, at or near the kneecap, the most versatile.
- Midi, mid calf, avoid stopping at the widest part of the calf.
- Maxi, near the ankle, make sure the hem clears your shoes.
