Checking garment sizing across supplier options

A medium from one print-on-demand blank is not necessarily a medium from another. To compare options, check the product-specific guide for a Printify item against the guide for the exact blank selected from ShirtSpace, where the range includes Gildan, Hanes and Bella+Canvas.

Match measurements, not size labels. Printify’s Help Center lists “Where can I find size guides?”; the comparison needs each product’s actual chart, not just a help page or a brand name.

Build a comparable measurement table

For each exact product, record its product code, size and chart figures for chest, body length and sleeve where provided. Note whether each figure describes the garment or the body, whether it is laid-flat or around-body, and whether the units are centimetres or inches.

Compare the Printify product guide with the guide for the exact ShirtSpace blank selected. ShirtSpace lists more than 2,000 styles, including Gildan, Hanes and Bella+Canvas, so use a specific garment rather than treating a brand or size label as a match.

Compare like with like: use the same measurement definition and units. For jacket charts, chest, sleeve, shoulder and length may be relevant, with waist or hip measurements where provided; do not compare figures directly when methods or units differ.

Match each size label to the other chart’s closest measurements rather than pairing identical labels automatically. If the relevant dimensions do not align, keep the product guides separate and do not imply that the sizes are equivalent.

Order representative samples when the fit decision matters. Measure each sample using its guide’s method, then try it on a suitable range of wearers if possible.

Record a supplier’s stated tolerance where available. Do not substitute an assumed tolerance or use an unstated figure as a comparison threshold.

Publish the right guide

Show measurements for the actual product being sold, and explain how customers can compare them with a garment they own. A detailed supplier size chart displayed prominently can help reduce returns.

Avoid one generic “true to size” claim across supplier options. If two blanks have unmatched measurements, keep their product-specific guides separate rather than merging them.

Keep catalogue revisions and sample notes so support staff can identify which blank fulfilled an order when investigating sizing complaints. Treat sample fit as an observation, not a guarantee about every production unit, and repeat the check if the blank or print provider changes.
