Quilting graph paper
Half-inch squares with a heavier line every inch, for laying out blocks, borders and whole quilt tops to scale. Quilting spans several geometries, though, so this page also points you at the right grid for triangles and hexagons.

A ready-made scale
Let one square equal one inch of finished quilt and a Letter sheet covers about 16 by 21 inches at half-inch squares — a single block at generous size, or a full throw if you let one square equal two inches. Because the print is true size, you can lay a rotary ruler straight on the sheet and measure.
Half inch for blocks, quarter inch for detail
Half-inch squares suit block layout and quilt-top planning: big enough to write in, few enough to count at a glance. Drop to quarter-inch when you are working out the piecing inside a single complex block and need the finer resolution. Both print at true size, so you can move between them without rescaling anything.
Seam allowance is not on the paper
Quilt blocks are drawn at finished size; the quarter-inch seam allowance is added when you cut. Drawing allowances into the plan is a common early mistake and makes every block finish small. Plan finished, cut with allowance.
Match the grid to the piecing
Squared paper handles rectangular piecing well and nothing else. For half-square and equilateral triangles use the triangle grid; for English paper piecing and hexie quilts use hexagon paper; for tumbling blocks and other 3D illusions use isometric paper, where the diamond is already drawn for you. Planning 60° shapes on square paper is the single most common reason a pieced design does not come out as drawn.
Printing it accurately
This only measures correctly if your printer doesn't rescale the page. In the print dialog set Scale: 100% — not "Fit to page" or "Shrink oversized pages". If you're not sure it worked, print the calibration page, measure the ruler on it with a real ruler, and it will tell you exactly what your printer is doing to the page.
