The grid method is how artists copy a reference picture at any size: rule the same number of squares over the photo and over the paper, then draw what is in each square. This grid maker does the photo half: create a grid over the reference and the drawing grids on paper or canvas follow the same count, whether the artwork is a portrait or a landscape. It is a generator for the photo side only - the paper is yours to rule. Pick a picture and a square grid is laid over it at once; Columns sets how many cells fit across, the cells stay square and the rows follow, with the last row partial when the picture does not divide evenly, exactly as a ruled sheet of paper would. Labels put letters along the top and numbers down the side in a white margin outside the picture, so a cell is called C4 on the photo and C4 on the paper and nothing of the picture is hidden. The stage info card gives the cell size in pixels and what that cell measures on A4 paper with the picture fitted to the page, so the paper grid can be ruled to match. This draws the grid over the picture; to actually cut the picture into the cells, use the image splitter.
Line width sets the lines in pixels for a 1000-pixel-wide picture and scales with the photo, so the grid is as visible on a phone snapshot as on a large scan. Line colour offers black, white, red, blue and green plus a custom picker, since black lines vanish on a dark reference and white ones on a bright one. Diagonals draws an X through every cell, the finer guide for placing curves and angles that some drawing tutors teach. Fade photo lightens the picture towards white so the lines read on a busy image and so a printed reference uses less ink; at a high setting the result is a pale image to draw over directly. The grid is redrawn at full resolution in the download, never scaled from the preview.
Download as JPG for a compact print-ready copy, PNG for exact lines, or WebP for the smallest file. A photo that came in as JPG saves as JPG by default; the format menu changes it. The pencil next to the file name renames the download, the copy button puts the gridded picture on the clipboard, and on a phone the share button sends it to another app or to a printer.
The reference photo never leaves your device. The picture is decoded in your browser, the grid, labels and diagonals are drawn on a canvas on your own processor, and the download is assembled there too. There is no upload, no account and no server-side copy.
Enough that each square holds one simple shape and not more. Eight to twelve columns suits most portraits and still lifes; a detailed scene may want twenty. Fewer, bigger squares are faster to rule and less to count but leave more to judge by eye inside each cell.
Match the count, not the size. If the photo has 8 columns and 6 rows, divide the width of your drawing area into 8 equal squares and let the rows follow. The stage info card also gives the cell size on A4 with the picture fitted to the page, which is the ruler measurement for that paper.
Yes. Download it as JPG or PNG and print it, or share it straight to a printer from a phone. Raise Fade photo before downloading if the reference is dark, so the lines stay visible on paper and the print uses less ink.
No. The photo stays in your browser from the moment you pick it to the moment you save the gridded copy. Nothing is transferred, stored or seen by anyone else.
