Size tank tops and crop tops by chest width and body length, and treat crop length as a separate design choice that you fix on the sample. For a first order, weight the size split towards the middle sizes and keep the smallest and largest sizes light until you have sales data.
A crop top size chart for brands needs more than S, M and L. It needs the measurements your buyers will compare against their own clothes, written from the approved sample. This post explains the measurements we work with, how to choose a crop length, and how to plan size ratios within our 100-piece minimum per style.
Size ranges by style
Our sleeveless styles come in these adult size ranges:
| Style | Sizes |
|---|---|
| Tank top | XS to 2XL |
| Muscle tee | S to 3XL |
| Crop top | XS to 2XL |
| Ribbed vest | XS to 2XL |
You do not have to order every size. Sizes can be mixed within a style in any ratio, so a fashion brand might order XS to L only, while a gym brand might start at S and go up to 3XL in muscle tees. The styles are on our white label tank tops page.
The measurements that matter
For sleeveless tops, these are the points to include in your size chart. All are measured flat.
- Chest: across the body, just below the armhole. The main fit measurement.
- Body length: from the high point of the shoulder to the hem.
- Hem width: across the hem. On a fitted crop or vest it is narrower than the chest; on a boxy crop or muscle tee it is about the same.
- Armhole depth: from the shoulder point to the base of the armhole. Important for tank tops and muscle tees.
- Strap width: on tank tops, measured at the shoulder.
On rib knit and cotton-elastane, the flat measurement is smaller than the body it fits, because the fabric stretches. Tell your buyers this in the size chart, for example “fitted, stretches to fit”, so they do not size up by mistake.
Choosing a crop length
Crop length decides where the hem sits on the body, and a small change makes a big difference. We confirm the crop length at quotation and you check it on the sample. Three common choices:
- Short crop: sits well above the navel. A fashion look, usually fitted, in rib or cotton-elastane.
- Mid crop: sits around the navel. The most versatile length for sale online, as it works with high-waist jeans, joggers and leggings.
- Long crop: sits just above the waistband of mid-rise bottoms. Suits buyers who want a cropped look with more coverage.
Decide whether the crop length grows with the size. Usually it does, by a small step per size, so the hem sits at the same point on the body across the range. If you want the same length in every size, tell us.
Write the crop length in words on your listing as well as in centimetres, for example “sits at the navel on our model, who wears size S”. Buyers understand that faster than a number.
Planning a first-order size ratio
With a minimum of 100 pieces per style, size ratios matter. Too many in the end sizes and stock sits unsold; too few in the middle and you sell out of the sizes people want.
Here is one way to split 100 pieces for a first order. Treat it as a starting point, not a rule.
| Size | Fashion crop top (XS to XL) | Gym muscle tee (S to 3XL) |
|---|---|---|
| XS | 15 | – |
| S | 25 | 15 |
| M | 30 | 25 |
| L | 20 | 25 |
| XL | 10 | 20 |
| 2XL | – | 10 |
| 3XL | – | 5 |
| Total | 100 | 100 |
If you already sell other garments, use your own sales by size instead. Your T-shirt or legging sales are a better guide than any general table. If you split the 100 pieces across colours too, keep the size ratio the same in each colour so stock stays even.
Grading and fit consistency
Grading is how the pattern steps up from one size to the next. On white label styles, our grading is already set, so each size follows the same proportions. What you should check is that the fit looks right at both ends of your range. If you can, try the sample on someone at your smallest and largest size, not only the middle.
Writing the chart for buyers
Once you approve the sample, we send you its measurements. Use them to write your chart, and keep it simple:
- chest, length and (for crop tops) crop length per size;
- the model’s height and size in photos;
- a line on stretch and fit;
- how to measure, in one sentence.
If you sell on a marketplace, confirm its size-chart format with the marketplace. Our minimum order and samples page explains how samples and size splits work across our range.
Send us your style, preferred crop length and planned size split, and we will quote it and confirm the measurements on your sample.
