Romper Size Chart
The broad adult romper chart runs from XS to XXL, with bust from about 31 to 45 inches, waist from about 24 to 38 inches and hips from about 34 to 48 inches. Find the row that covers your largest measurement, then check the brand chart, because brands grade rompers differently and the chart below is a general guide, not a brand size.
How to read the romper size chart
A size chart is a set of body measurement ranges, not a set of garment measurements. Each row gives the bust, waist and hip numbers that a size is cut for, and your job is to find the row that covers your own numbers. Start by measuring bust at the fullest point, waist at the narrowest point and hips at the widest point, with a soft tape kept level and worn over light clothing.
Do not pick a row from one measurement alone. If your bust sits in S, your waist in M and your hips in L, the chart is telling you that your body spans three rows, and you need a rule for choosing between them. The usual rule is to start with the largest of the three, because a romper must fit the widest area that affects it, and a tight bodice or thigh pulls the whole garment out of place.
The general chart in inches
The table below gives broad adult bust, waist and hip ranges in inches for sizes XS to XXL. Treat these as starting ranges, not as brand sizes, and always check the brand chart for the romper you are buying. Two brands can use the same size letters with different ranges, so the letter alone tells you very little without the numbers behind it.
If your measurements fall below XS or above XXL, the chart cannot give you a precise starting size. Use the nearest end of the chart as a rough guide and rely on the brand chart and the stated garment measurements instead. The Romper Size Calculator uses the same ranges to estimate a starting size from your numbers.
The same chart in centimetres
Centimetres help when a brand lists its chart in metric units, and they also help when your tape is metric. An inch is 2.54 centimetres, so a bust of 35 inches is about 89 centimetres and a waist of 28 inches is about 71 centimetres. Convert your own measurements first, then compare them with the metric row, rather than converting each chart row in your head while you shop.
Watch for rounding when you convert. A brand that rounds its metric ranges can shift a borderline measurement from one size to the next, so a measurement that sits on a boundary in inches may sit clearly inside a size in centimetres, or the other way round. When you sit on a boundary, check the torso length and the fabric before you decide, because those two factors often settle a close call.
What the chart does not tell you
A bust, waist and hip chart does not cover torso length, inseam or thigh fit, and for a romper those three matter as much as the three numbers in the chart. A torso under about 26 inches is short and over about 29 inches is long, as a rough guide, and a romper with the wrong torso length will pull or sag no matter which row your bust, waist and hips point to.
The chart also says nothing about fit intent. A fitted romper in your chart size will feel close through the bodice and shorts, while a relaxed romper in the same size will feel loose, because the designer built different amounts of ease into each style. Read the fit note beside the chart, check the stated inseam, and compare the garment length with your own torso length before you order.

Frequently Asked Questions
What size is a 35 inch bust in a romper?
In the broad chart, a 35 inch bust sits in M, with a waist of 28 to 29 inches and hips of 38 to 39 inches. Check the brand chart, because brands grade differently.
Should I use my largest measurement?
Yes, as a starting rule. Start with the size that fits your largest of bust, waist and hips, then check the bodice and thigh separately.
Are romper size charts the same across brands?
No. Brands grade their sizes differently and cut for different torso lengths and inseams, so always compare your numbers with the brand chart.
What if I fall between two chart rows?
Look at torso length and fabric. A firm fabric usually points to the larger size, while a stretchy fabric can sometimes take the smaller size when the torso still fits.
Does the chart cover torso length?
No. The chart covers bust, waist and hips only. Measure torso length separately and compare it with the stated garment length.
How do I convert inches to centimetres?
Multiply inches by 2.54. A 35 inch bust is about 89 centimetres, and a 28 inch waist is about 71 centimetres.
