Scale a reference photo to a wall with proportional artwork dimensions, full-cell sizes and enlargement from the printed reference. Start with your photo or the botanical example.

Compare the original image, its gridded reference and the matching blank sheet. Each pair keeps the same proportions, labels and partial final row.
Source image: 1536 × 1024 px
12 columns × 8 rows · Cell: 22.75 × 22.75 mm
A4 · Landscape · Paper margin: 10 mm · 300 DPI
Artwork: 3,000 × 2,000 mm · Each full cell on your wall: 250.0 × 250.0 mm
Enlargement from printed reference: 10.99×. Use the same grid counts on both surfaces.
Upload your image or load the botanical mural example. Mural settings open first; the example uses 12 square columns and an A4 landscape reference with 10 mm margins.
Enter your target width in millimetres. Height follows the source image ratio. Full wall-cell width is target width divided by columns; enlargement is target width divided by printed image width.
Print the reference at 100%, check a cell and mark the calculated intervals on the wall. Match labels and contours; preserve a shorter final row if shown.
Start with 4–6 columns for simple outlines, try 8–12 for everyday drawing practice, and add more for complex detail as needed. Column count sets the drawing sections; DPI sets output pixels and print fineness. Increasing DPI does not add missing photo detail.
It is the width of the artwork. Height is calculated from the photo, so the artwork may not fill your entire wall. Measure the available space before marking the grid.
This calculator provides wall measurements and a one-page reference. It does not create a tiled multi-page wall-size print. The enlargement factor compares the wall artwork with the fitted printed image, not with source pixels.

Create a matching blank grid drawing worksheet from a reference photo. Pair the labeled reference and practice sheet, then export a paper-sized PDF or PNG.
Learn to select a reference, choose a grid, prepare paper, place landmarks, copy one cell at a time and gently remove pencil guides.
