Sample chart: a strawberry, 30 × 30 knots (8 × 8 in on 3.75-mesh latch hook canvas) in 12 DMC colors. Every cell is filled, background included, since latch hook is usually worked edge to edge. Choose a photo to chart your own at 60 knots wide.

Share of yarn is each color's part of all knots. How much yarn that is depends on your yarn weight and tension: work a 10 × 10 swatch, weigh or measure the yarn it used, and scale by these counts. Thread and bead colors on screen are approximations of the real material.

What this latch hook pattern maker makes
Latch hook rugs and wall hangings are worked on a coarse canvas with one knot of pre-cut yarn in every hole. At 3.75 holes per inch the grid is coarse, so designs should be bold: pets, initials, simple landscapes.
Each knot uses one piece of cut yarn, so the knot count per color in the key is also the number of yarn pieces to cut or buy.

How big a latch hook chart comes out
Finished width = knots × 6.77 mm. The table uses the nominal grid (3.75-mesh latch hook canvas); real pieces vary slightly with the material, your yarn and your tension.

|---|---|---|---|
| 45 latch hook knots | 30.5 | 12.0 | 2,025 |
| 60 latch hook knots | 40.6 | 16.0 | 3,600 |
| 90 latch hook knots | 61.0 | 24.0 | 8,100 |
| 120 latch hook knots | 81.3 | 32.0 | 14,400 |
Knots for common rug and cushion sizes
At 3.75 holes per inch, every square inch takes about 14 knots (3.75 × 3.75). Each knot is one piece of cut yarn.

| Small wall hanging, 12 × 12 in | 45 × 45 knots | 2,025 |
| Cushion front, 16 × 16 in | 60 × 60 knots | 3,600 |

How to read a latch hook chart
Each square is one knot. Work in rows from the bottom of the canvas up, so the pile from finished rows falls away from the row you are hooking.
Keep the printed chart beside you and mark the canvas with a marker every 10 holes to match the chart grid lines.
Materials for latch hook charts
- 3.75-mesh rug canvas, cut with a margin of several holes on every side for hemming.
- Pre-cut rug yarn or acrylic yarn cut to equal lengths, one piece per knot.
- A latch hook tool and a permanent marker for grid lines.
- Rug binding tape or a backing fabric for the finished edge.

Tips for latch hook charts
- Cut all yarn of one color before you start so the pile height is even.
- Pile hides fine detail; a 3.75-mesh canvas cannot show thin lines, so thicken outlines in the image first.
- The DMC numbers in the key are a color guide only; rug yarn colors are named differently.
- Bind the edges before using the piece as a rug, or the outer knots will work loose.

Each page lists the color's hex value and its nearest equivalents in other brands by CIEDE2000.
