Selling gang sheets on a Shopify shop

How a customer builds a sheet on your shop

A Shopify product holds a price and a quantity. It does not hold the customer's designs, so a gang sheet product needs a builder on its product page. The customer adds their designs and sets the size of each one. They are placed across your film width, and the order arrives with the finished print file.

Shop owners often ask for the same job in two forms. One customer uploads a logo and wants it repeated to fill the sheet, for example 20 small copies or 6 large ones. Another wants to choose a sheet size and place several different designs on it. A builder that takes a design and a number of copies covers both.

The file you need on each order

Printers ask for a PNG with a transparent background at 300 DPI, at the size it will print. A JPG has no transparency, so the white or coloured background prints as well. Some printers also take a PDF. Check that the file on the order is the whole sheet at full size, ready for your RIP software, and that any design below 300 DPI is flagged before the customer pays.

Our DTF file requirements guide covers transparency and resolution in more detail.

Selling by length when you run out of variants

A gang sheet can be any length, and one variant for every length soon reaches Shopify's variant limit. The usual answer is one variant priced for a unit of length, such as 10 cm, with the quantity carrying the length. A 1.2 m sheet sold per 10 cm is a quantity of 12. With a builder app, the length of the customer's layout sets the quantity, so they never type it.

The other way is a short list of fixed sheet sizes, each a variant with its own price.

Of the UK printers we list, 32 of 50 (64%) sell film by length. In the US, 239 of 246 (97%) sell fixed sheet sizes. Prices checked 4 October to 5 November 2026.

Film width

Set the builder to the width your printer can print across, which can be a little less than the roll. A design wider than that cannot go on the sheet, so the builder should stop it before the customer pays.

• UK: 560 mm is the width used by 21 of 50 printers we list.
• US: 559 mm (22 in) is the width used by 192 of 246 printers we list.

What printers charge for film

For one metre of film at that width, the middle figure across the printers we list, before delivery:

• UK: £12.00 a metre, with the middle half of printers at £8.99 to £14.40. Including VAT where the printer charges it. Checked 4 October to 5 November 2026.
• US: $24.00 a metre, with the middle half of printers at $20.00 to $32.00. Before sales tax. Checked 8 October to 5 November 2026.

Each printer, its price, the date we checked it and its source are on our DTF price summary.

The builder looks like the phone version on a computer

A builder placed inside a page with a narrow content column has only that column's width, so it switches to its phone layout. Put it on a product template, or give its section the full page width in the theme editor.

A gang sheet builder showing on your other products

An app block added to the default product template appears on every product that uses that template. Make a separate product template for gang sheets, add the builder block there, and assign that template to your gang sheet products only. Your other products keep the default template, with its own upload block if they need one.

An app for the builder

Layout Foundry Gang Sheets is our Shopify app for this. It puts the builder on your product page, sells by length or as fixed sheets, and puts the print file on each order. It is on our page for shops.
