GSM Ranges by Garment Type at a Glance

GSM ranges tell you how heavy a blank feels before you order it. Lightweight tees sit near 140 to 160 GSM, midweight tees around 180, hoodies between 280 and 400, and outerwear above 400. Reading a GSM range as a feel prediction rather than a quality score keeps product selection honest, because a 300 GSM fleece and a 300 GSM tee behave nothing alike.

Buyers often ask for the heaviest fabric they can get. The right answer depends on the print method, the season, and the price band, which is why a quick reference table earns its place in the tech pack.

The Reference Table

Lightweight jersey runs 140 to 160 GSM and suits summer tees and sublimated sports tops. Standard jersey at 170 to 190 GSM is the workhorse for DTG and DTF prints. Heavyweight jersey at 200 to 240 GSM flatters the boxy fit and holds a large chest print with less show through.

Move up and the GSM range widens fast. French terry starts near 260, fleece sits at 280 to 320, and a premium hoodie can reach 400. Above that you are in jacket territory, where the number matters less than the face fabric and the lining.

A printable version of the same numbers with print method pairings sits in our guide to GSM explained for custom apparel blanks. The structure behind how fabric GSM affects hoodie weight and returns is worth reading before you quote a fleece weight to a buyer.

Why Weight Changes the Print Outcome

Ink sits differently on every weight band. On a 150 GSM tee the fibre can show through a solid white print, and a heavier 200 GSM base covers it with fewer passes. That single difference pushes a GSM range choice into the costing conversation.

Drape follows the same logic. A lightweight base moves with the body and a heavy one holds structure, so the same cut reads as relaxed or boxy depending on the fabric weight. Our notes on fabric weight and drape for custom clothing explain how to match the two without a second sample round.

Heat settings are weight sensitive too. A thick fleece absorbs heat differently from a thin jersey, and the parameters in heat press temperature guide by fabric type assume you know which band you are pressing.

Season and Product Pairing

Spring and summer lines sit in the 140 to 190 GSM band, with a few heavier pieces for structure. Autumn and winter move to 250 GSM and above, where the garment is expected to hold warmth. Picking a GSM range outside the season is the fastest way to end up with dead stock.

Jackets complicate the table because the outer shell and the lining each carry a weight. A 320 GSM shell with a light lining feels different from a 260 GSM shell with a heavy one, and the seasonal pairing logic in fabric weight guide for custom jackets by season covers how to read both numbers together.

Sublimated sportswear runs lighter than the categories above. A jersey that needs to stretch and breathe sits lower than a streetwear tee, and the target band for that product family appears in which GSM works best for custom sublimated jerseys.

How to Use the Numbers in Buying

Ask for the GSM range from the supplier in writing, not from a product title. Listings quote the fabric mill's nominal weight, and the finished garment after washing may sit lower by a few percent, which matters when a buyer is comparing two similar styles.

Then compare within category, never across it. A 180 GSM tee and a 180 GSM dress shirt are not interchangeable products, and using one GSM range as a universal benchmark produces decisions nobody can defend at a trade show.

Two reference details save arguments later. Every GSM range quoted in a listing is a nominal figure, and the finished weight after washing and finishing can land a few percent lower. Knit and woven fabrics inside the same GSM range also feel different, because the structure carries as much of the hand as the weight does. Note both points on the spec sheet and the table stays useful across suppliers.

Common Selection Errors

Choosing the heaviest option for perceived quality is the first error. Heavy blanks cost more, ship heavier, and can feel stiff to a buyer who expected a soft hand.

Skipping the sample is the second. GSM numbers narrow the field; a washed sample confirms the choice. One garment per candidate base is enough, and it prevents a full order built on a spec sheet.

The third is ignoring shrinkage, which shifts the weight per square metre after the first wash. The tolerances in our guide to fabric shrinkage and pre-shrinking explained are the companion document to any GSM range table.

Keep one GSM range table per product family, confirm each number in writing, and sample before you commit to a season. If you want to compare blanks across these bands, browse our custom product catalogue and order the two weights you are deciding between.
