Use garment measurements
Common points include chest width, body length, shoulder width, sleeve length and sleeve opening. State whether measurements are taken flat and whether chest is half or full circumference.
A size label such as M or L is not enough because fit standards differ between brands. A measurement chart gives the manufacturer and customer a clear reference.
Define the fit
Regular, relaxed, slim and oversized fits need different ease. Compare the chart with a physical reference garment that matches your intended silhouette.
Add tolerance
Knitted garments can vary slightly after cutting, stitching and finishing. Confirm an acceptable measurement tolerance with the manufacturer.
Recommended solution
Approve every size on a graded pattern or size set before bulk cutting. Publish the same chart on the product page and include guidance on how customers should measure a well-fitting T-shirt.
Key takeaway for clothing brands
Use this T-shirt size guide for manufacturing as a planning framework, then confirm the final fabric, construction, branding and production details through a physical sample. Written specifications and an approved reference reduce avoidable changes during bulk manufacturing.
