Free DTF Gang Sheet Builder — Auto-Arrange Designs, Minimize Waste
A gang sheet combines multiple DTF designs onto a single transfer film, dramatically reducing your cost per print. Instead of ordering individual transfers at $2-5 each, a well-arranged gang sheet can bring your cost per design down to $0.50-1.50 depending on size and quantity.
This free DTF gang sheet builder automatically arranges your designs on a sheet using the MaxRects algorithm — the same packing technology used by professional DTF software. Upload your designs, set dimensions and quantities, and hit Optimize Layout to see exactly how much film you save.
How to use the gang sheet builder
Set your sheet width (22", 24", and 30" are standard DTF roll widths). Upload your design files in PNG, JPG or WebP format. Set the width, height and quantity for each design. Click Optimize Layout — the tool tests multiple arrangements and picks the one with minimum waste. Download your print-ready 300 DPI PNG and send it to your supplier.
What is the MaxRects algorithm?
MaxRects is a rectangle packing algorithm that finds near-optimal arrangements for multiple rectangles in a given container. It tracks all available empty spaces as rectangles and fills them efficiently. The result is significantly less wasted film compared to manual arrangement — typically 20-40% improvement on mixed-size design sets.
Gang sheet tips for Etsy and Shopify sellers
Batch your orders before sending to your supplier — combine designs from multiple orders onto one gang sheet. A 22×36 inch sheet from most suppliers costs $8-15 and can fit dozens of small designs. The more designs you can fit, the lower your cost per unit and the better your profit margin on each sale.
Frequently Asked Questions
What is a DTF gang sheet?
A gang sheet is a single DTF transfer film that contains multiple designs arranged together. Instead of ordering one transfer at a time, you combine all your designs onto one sheet and print them together. This dramatically reduces your cost per design.
What sheet widths are standard for DTF?
Standard DTF roll widths are 22 inches, 24 inches, and 30 inches. The length (height) is flexible — your supplier charges by the linear foot. This tool auto-calculates the minimum height needed to fit all your designs.
What file format does the download produce?
The builder downloads a print-ready PNG file at 300 DPI — the standard format accepted by all DTF suppliers. The white sheet background represents the actual transfer film.
What does the Optimize Layout button do?
Optimize Layout runs the MaxRects algorithm which tests 5 different arrangement strategies and picks the one that results in the shortest sheet height and lowest film waste. It typically saves 20-40% compared to the initial auto-arrangement.
Should I use PNG with transparent background for DTF designs?
Yes. PNG with transparent background is the correct format for DTF designs. Transparent areas will not transfer to the garment — only your design will print. White areas in your design will print as white ink underbase.
What does the BG toggle do in the builder?
The BG (background) toggle simulates how your design will look on the transfer film. When BG is off, transparent areas show as white (the film color). When BG is on, it shows a grey background so you can see the transparent areas in your design.
