Jumpsuit Sizes: How to Get the Torso, Bust and Hip Right
A jumpsuit has to fit your bust, waist, hip, leg and the vertical length of your torso all at once, which is why it is the hardest garment to buy online. This page shows the measurements that matter, in which order, plus rompers, petite and tall cuts, and children's sizes.
Choose a jumpsuit by the larger of your bust and hip size on a standard women's chart (a medium fits about a 36.5-37.5 in bust and 38.5-39.5 in hip, or 93-95 cm and 98-100 cm), then check the torso length: if you are taller than about 5 ft 7 in (170 cm) or long-waisted, look for a tall or long-torso cut. Children's jumpsuits use age or height sizes, where a size 98 fits a child about 98 cm (38.5 in) tall, typically 2-3 years.
- Women's M bust
- 36.5-37.5 in
- Women's M hip
- 38.5-39.5 in
- Kids' size 98
- 98 cm, age 2-3
- Full-length inseam

Women's jumpsuit size chart
Jumpsuits use the standard women's size chart. The difference from a dress is that two independent fit points, the top and the trousers, are joined by a fixed length, so you check more measurements before deciding.
| Letter | US | UK / EU | Bust | Waist | Hip |
|---|---|---|---|---|---|
| XS | 0-2 | 4-6 / 32-34 | 32.5-33.5 in (83-85 cm) | 24.5-25.5 in (62-65 cm) | 34.5-35.5 in (88-90 cm) |
| S | 4-6 | 8-10 / 36-38 | 34.5-35.5 in (88-90 cm) | 26.5-27.5 in (67-70 cm) | 36.5-37.5 in (93-95 cm) |
| M | 8-10 | 12-14 / 40-42 | 36.5-37.5 in (93-95 cm) | 28.5-29.5 in (72-75 cm) | 38.5-39.5 in (98-100 cm) |
| L | 12-14 | 16-18 / 44-46 | 39-40.5 in (99-103 cm) | 31-32.5 in (79-83 cm) | 41-42.5 in (104-108 cm) |
| XL | 16-18 | 20-22 / 48-50 | 42-44 in (107-112 cm) | 34-36 in (86-91 cm) | 44-46 in (112-117 cm) |
Individual numeric sizes and plus ranges are on the dress size chart. Expect brands to differ by about 1 in on each measurement.
The order to check measurements
- Start with the larger of bust and hip. These are the measurements a jumpsuit cannot fake. Whichever falls in the larger size sets your starting point.
- Check the torso length. Compare your torso loop (below) with the brand's figure, or with a jumpsuit you own. Too short is the most common failure and the hardest to fix.
- Look at the waist last. Most jumpsuits have a belt, drawstring, elastic or wrap, so the waist can usually absorb a difference of one or two sizes.
- Check the inseam. Full-length jumpsuits are typically cut with a 28-32 in (71-81 cm) inseam. Hemming is easy; letting down is usually impossible.
The crotch sits too high or cuts in when you sit, the shoulder straps dig in or slide off when you raise your arms, and the waist seam sits above your natural waist. Going up a size adds mostly width and very little length, so a long torso needs a tall or long-torso cut, not just a bigger size.
How to measure your torso for a jumpsuit
Jumpsuit brands that publish a torso measurement almost always mean the torso loop, sometimes called torso girth. It is the same measurement used for one-piece swimsuits.
- Start at the shoulder. Place the end of the tape on top of one shoulder, halfway between neck and shoulder point, where a strap would sit.
- Run it down the front over the bust, through the crotch and up the back.
- Return to the start point and read the total. Keep the tape snug but not tight, standing straight.
Most adult women measure roughly 56-66 in (142-168 cm). Below about 58 in, petite jumpsuits fit better; above about 62 in, look for tall or long-torso styles. A quicker check is to compare your height: petite cuts are designed for 5 ft 4 in (163 cm) and under, tall cuts for 5 ft 8 in (173 cm) and over. The swimsuit fit guide uses the same torso measurement for one-pieces.
Petite, regular and tall jumpsuits
| Cut | Designed for | Typical inseam | What changes |
|---|---|---|---|
| Petite | 5 ft 4 in (163 cm) and under | 26-28 in (66-71 cm) | Shorter bodice, rise and leg; narrower shoulders |
| Regular | 5 ft 4 in - 5 ft 7 in (163-170 cm) | 28-31 in (71-79 cm) | Base pattern |
| Tall | 5 ft 8 in (173 cm) and over | 32-35 in (81-89 cm) | Longer bodice, rise and leg |
| Cropped / culotte | Any height | 21-26 in (53-66 cm) | Leg ends at mid-calf or ankle on purpose |
If you are tall but only need more leg, a two-piece co-ord set in matching fabric solves the torso problem entirely. For trouser inseams by height, see the pant size chart.
Jumpsuits, rompers, boiler suits and onesies
- Jumpsuit: full or cropped trouser legs. Sized as above.
- Romper / playsuit: shorts instead of trousers, usually a 2-5 in (5-13 cm) inseam. Torso length matters just as much; inseam does not.
- Boiler suit / utility jumpsuit: cut boxier with a zip or button front. Fashion versions follow women's sizes; workwear versions are sized by chest, covered in the overalls and coveralls guide.
- Adult onesie (lounge or pajama): loose and stretchy, usually sized S-XL with a height band for each size. Height matters more than width here, so pick the size whose band includes your height even if it looks roomy.
Strapless and halter jumpsuits rely on a close bust fit to stay up, so size those by bust first and have the hip let out only if there is seam allowance. During pregnancy, look for maternity jumpsuits with extra length in the front rise; the maternity clothes guide explains why regular ones stop fitting early.
Kids' jumpsuit and romper sizes
European children's sizes are the child's height in centimeters, as defined by EN 13402. US sizes use age. A label of 98 means the garment is cut for a child about 98 cm tall.
| EU size | Child height | Typical age | US size |
|---|---|---|---|
| 74 | 74 cm (29 in) | 6-9 months | 6-9M |
| 80 | 80 cm (31.5 in) | 9-12 months | 12M |
| 86 | 86 cm (34 in) | 12-18 months | 18M |
| 92 | 92 cm (36 in) | 18-24 months | 2T |
| 98 | 98 cm (38.5 in) | 2-3 years | 3T |
| 104 | 104 cm (41 in) | 3-4 years | 4T |
| 110 | 110 cm (43.5 in) | 4-5 years | 5 |
| 116 | 116 cm (45.5 in) | 5-6 years | 6 |
| 122 | 122 cm (48 in) | 6-7 years | 7 |
| 128 | 128 cm (50.5 in) | 7-8 years | 8 |
Choose by height rather than age, because children of the same age can differ by 10 cm or more. For one-piece garments, a child near the top of a size range is better in the next size up, since the body length runs out before the width does. Toddler jumpsuits with snaps at the crotch are less sensitive to torso length than adult ones.
Frequently asked questions
Should I size up in a jumpsuit?
Size up if you are long in the torso or between sizes in a woven fabric with no waist adjustment. A jumpsuit that is too short in the body pulls at the crotch and shoulders, and that cannot be altered, while extra width at the waist can be belted or taken in.
What are the measurements of a size 98 kids' jumpsuit?
Children's size 98 is cut for a child about 98 cm (38.5 in) tall, usually around 2-3 years old. Sizes step every 6 cm, so the next sizes are 92 and 104. It is the European equivalent of US 3T.
How do I measure for a jumpsuit?
Take your bust, natural waist and hip as for a dress, then your torso loop: from the top of one shoulder, down the front, through the crotch and back up to the same shoulder. Add your inseam if the jumpsuit has full-length legs.
What is the difference between a jumpsuit and a romper?
A jumpsuit has long or cropped trouser legs; a romper (called a playsuit in the UK) has shorts. Both are sized the same way, but a romper has a 2-5 in inseam, so leg length never decides the size.
How are work jumpsuits sized?
Work coveralls and boiler suits are sized by chest in inches (38, 40, 42 and so on) with short, regular and tall lengths, or by S-3XL. The full chart is in our overall and coverall size guide.
