How to Calculate Tufting Canvas Size
Buying the right canvas size for tufting is critical — too small and you can't stretch the canvas properly on the frame, too large and you waste expensive tufting cloth. This tufting canvas calculator adds the correct edge allowance to your finished rug dimensions and shows the exact hole grid for transferring designs.
Step 1: Enter your finished rug dimensions
Enter the width and height of the rug you want to make — not the canvas. The calculator adds the edge allowance needed for stretching and attaching the canvas to your tufting frame.
Step 2: Choose your canvas type
Monk's cloth (3.7 holes/in) is the most common beginner choice — soft and flexible. Primary tufting cloth (4.0 holes/in) gives a tighter grid for detailed patterns but requires more consistent gun speed. Standard tufting cloth (3.5 holes/in) is a good all-around choice for gun tufting.
Step 3: Use the hole count to scale your design
The design columns and rows tell you how many holes your design area spans. Scale your artwork to this grid — each hole becomes one "pixel" in your tufted design. For a 24-inch wide rug on 3.7 holes/in canvas, you have 89 holes across the design area to work with.
Frequently Asked Questions
Is this tufting canvas calculator free?
Yes, completely free with no signup required. Enter your finished rug size and canvas type for instant measurements.
Is my data safe and private?
Yes. All calculations run locally in your browser. No data is sent to any server.
How much extra canvas do I need beyond the rug size?
Add at least 3–4 inches (7.5–10 cm) on each side for a simple design, or 4–5 inches (10–13 cm) for detailed designs. This allowance lets you stretch and staple the canvas to a tufting frame without the design area getting too close to the edge.
What is the difference between monk's cloth and primary tufting cloth?
Monk's cloth has about 3.7 holes per inch and is softer and more flexible — good for hand tufting and beginners. Primary tufting cloth is woven more tightly at about 4 holes per inch, giving a more stable grid that holds pile tufts firmly. Both work with tufting guns; primary cloth handles faster work better.
How do I transfer my design to tufting canvas?
Print or trace your design scaled to the canvas dimensions. Lay the canvas flat and trace the design using a Sharpie marker — the grid holes make alignment straightforward. Work in sections for large designs. Light table or a bright window behind the canvas makes tracing easier for detailed work.
How many holes per square inch does tufting cloth have?
Monk's cloth has ~13.7 holes/sq in (3.7×3.7). Standard tufting cloth has ~12.25 holes/sq in (3.5×3.5). Primary tufting cloth has ~16 holes/sq in (4×4). Higher hole density gives finer detail but requires thinner yarn and slower gun speed.
