On-Point Quilt Planner for a Diagonal Set You Will Sew

An on-point quilt planner should show blocks as diamonds, with setting triangles that keep straight grain on the edge. Quiltler rotates the grid and keeps finished size on screen. Design is free; one saved quilt and two fabrics.

People search on-point quilt planner when squares sit on their point, not on their side. Quiltler’s layout can rotate a square grid; the edge fill is still a setting-triangle job. Design in the studio. Cut math for those triangles is the free setting triangle calculator. Straight-set layouts stay on quilt layout software. Size names are in the quilt sizes guide.

What this page actually plans

Quiltler desktop quilt design studio: setting quilt size and block grid, then placing blocks and fabrics on the canvas
The studio keeps finished size visible while you add blocks, sashing and borders.

On-point is a setting, not a personality

The same nine-patch can sit straight or on point. On point makes the block a diamond and needs triangles (and usually corner triangles) so the quilt has a straight outer edge. If you skip those, you have a zigzag edge you probably did not want.

Quiltler shows the rotated grid. You still cut setting triangles from the calculator so the straight grain sits on the perimeter. Do not use the half-square triangle calculator for that edge — those are piecing triangles, not setting triangles.

Borders after an on-point centre still change finished size. Watch the number.

Yardage on the canvas follows pieces. Binding and backing in the pack are subscription.

Straight set versus on point

Straight set is rows and columns of squares. On point is rows of diamonds. Same blocks, different yardage of background. If you only need ‘a quilt of HSTs,’ the half-square triangle quilt planner may be the simpler job.

Cornerstones and sashing still work. They just follow diamond meetings.

Yardage and free limits

Background for setting triangles is real fabric. Count it. The studio’s fabric total includes pieces you drew; the calculator covers triangles you have not drawn yet.

Two fabrics on free: often block plus background. One saved quilt for the on-point experiment you will actually sew. Setting triangles keep straight grain on the quilt edge; HSTs do not. Cut those triangles from the calculator, not from leftover HST squares. Corner triangles are a different cut again. Foundation paper piecing inside a diamond is optional for sharp units in the pack.

Write the finished inches down, then open the matching backing, binding or batting answer if that size has one. Those pages do not replace the canvas: they cover the rectangle jobs. The pieced top is still counted in the studio. If one unit needs foundation paper piecing, the pack can print sheets after you subscribe; a nine-patch field does not. Keep the free limit in mind: one saved quilt and two photographed fabrics, plus solids, is enough to prove the plan before you cut a stack the shop will not take back.

Open the studio, rotate the grid, and keep the setting triangle calculator in another tab. That pair is on-point planning.

On-Point Quilt Planner FAQ

Does Quiltler calculate setting triangles automatically?

The setting triangle calculator is the dedicated math. The studio shows the on-point grid; you still cut from the card.

Are setting triangles the same as HSTs?

No. Setting triangles keep straight grain on the quilt edge.

Can I design on-point for free?

Yes. Two fabrics, one saved quilt, fabric total. Packs paid.

What about hexagon on-point?

Hex layouts are a different start. This page is square blocks on point.

Plan the on-point quilt in the studio

Rotate the grid. Count setting triangles. Read finished size before you cut bias wrong.
