Start from real streetwear measurements, edit them to match your sample, and export a size chart for your product page, Instagram or Shopify. Centimetres or inches.
These are starting measurements
The numbers come from LineDrop templates. Before you publish, measure your approved sample laid flat and type in your real numbers. A chart that doesn't match the garment means more returns.
Tick what shoppers should see. M is the base size: change M or the step and the other sizes follow. Type in any other cell to set it by hand. Values in cm, widths laid flat. The chart rounds to the nearest ½ cm.

Standard clothing size charts
If you need a starting point, these are the measurements most streetwear brands publish, in centimetres, taken with the garment laid flat on a table. Widths are half the garment, not all the way around. Check your own sample against them, then use the tool above to build the chart you publish — no two factories grade exactly the same way.

Every measurement above is a starting spec, not a standard anyone enforces. There is no legal or international clothing size standard — S at one brand is M at another — which is exactly why publishing your own measured chart matters.
How to make a size chart for your clothing brand
1. Start from your garment type
Pick the closest shape above. Boxy, oversized and fitted pieces grade differently, so start from one that matches your fit.
2. Measure your approved sample
Lay it flat on a table, smooth it out and measure each point with a tape. Type the size M numbers into the M column.
3. Check the step between sizes
Most tops change 2–3 cm across the chest (laid flat) per size. Your factory's grading, or your tech pack, tells you the real steps.
4. Pick what shoppers see
Three to five measurements is plenty: chest, length, shoulder and sleeve for tops; waist, hip, rise, inseam and leg opening for pants.
5. Export and publish
Add the PNG to your product images or paste the HTML into your Shopify description. Say clearly whether widths are laid flat or all the way around.
Yes. You can make, edit and export as many size charts as you like without an account. Free exports carry a small 'Size chart by LineDrop' credit; LineDrop Pro removes it.
Where do the starting measurements come from?
From LineDrop's tech pack templates, which list every measurement at size M and how much it changes per size. They are a starting point: measure your own approved sample and type in your real numbers before you publish.
Should I show garment or body measurements?
This tool makes a garment size chart: the measurements of the clothing itself. For boxy and oversized streetwear that is usually the most useful, because shoppers can compare it with a piece they already own.
Is there a standard clothing size chart?
No. Clothing sizes are not standardised — an S at one brand is an M at another, and there is no rule a brand has to follow. That is why shoppers look for the measurements rather than the letter, and why publishing a measured chart for your own garments cuts returns.
Can I use it on Shopify?
Yes. Use 'Copy Shopify HTML' and paste it into your product description using the code view (the <> button), or add the PNG to your product images. It also works with most size chart apps that accept an image.
Need the factory version too?
Every LineDrop template comes with a full tech pack: flat sketches, every point of measure with tolerances, fabric and sewing details, as a PDF for your manufacturer.
