Free Online Grid Maker

A grid maker lays a measured grid over your reference photo so you can copy it one cell at a time instead of judging the whole picture at once. This one sets the cells in real cm or inches rather than a bare number of squares, so the grid you export matches the grid you rule on your paper. Drop a photo below, set the cell size, and take it away as a PNG or a print-ready PDF.

  • Grid cells in real cm or inches
  • Drag the grid to fit your subject
  • True-to-size poster printing

How the Grid Maker Works

From photo to gridded reference in under a minute

01

Upload a reference

Drop in a photo, a painting, or a screenshot. JPG, PNG and WebP up to 20MB work, straight from your phone camera too.

02

Set up the grid

Choose the cell size in centimeters or inches, pick a line color that stays visible on your photo, and drag the grid until the lines sit where they help you.

03

Export and draw

Print the PDF or open the PNG on a tablet. Draw the matching grid on your paper and work through it cell by cell.

Everything the Grid Drawing Tool Can Do

Built for how artists actually work with grids

Cell size
0.1 to 100, in cm or inches, fractional values included.
Columns and rows
1 to 100 on each axis; change one and the other two recompute.
Canvas presets
18 in cm and 18 in inches, from DIN A5 to A0 and Letter to Arch C, plus any size you type in.
Composition overlays
Nine, from the rule of thirds to a golden spiral you can drag onto a face.
Checking your drawing
Nine comparison modes and up to 20 ruler lines across both images.
Poster print
Tiles across nine sheet sizes, A0 to A5 and Letter, Legal or Tabloid, with cut and glue guides.
Export
PNG, or PDF laid out for A4, A3, Letter or Legal.
Cell addresses
Columns run A to Z and on to AA, rows count from 1, so any cell has a name like B4.
Reference photo
JPG, PNG or WebP up to 20 MB, at least 300 by 300 pixels.

Two grid modes

In Grid on Image mode the grid lies directly on your photo and follows its real dimensions, which is right for working from a printed reference.

In Grid on Canvas mode you define the physical canvas first (DIN A0 to A5, US Letter, Legal or a custom size in cm or inches) and the photo is fitted inside it. The grid belongs to the canvas, so it matches the paper in front of you.

Change grid size, columns or rows and the other two values recompute automatically, fractional values included.

Grid on Canvas: pick A0–A5 or Letter and the photo is fitted to your real paper size.

Precision grid controls

Set the cell size in centimeters or inches, from 0.1 to 100, not just a number of squares.

Drag the grid with the mouse or a finger, or nudge the photo under it with the arrow keys, until the lines sit between the eyes instead of across them.

Coordinate labels give every cell an address like B4: columns run A to Z, rows are numbered. Useful for tutorials and classrooms.

In fullscreen, focus mode dims everything except the cells you select, so you draw one square at a time.

Every cell has an address: coordinates run A to Z across and 1, 2, 3 down.

Nine composition overlays

Nine overlays: rule of thirds, golden ratio, golden spiral, root-2 and root-3 rectangles, Loomis horizon, center cross, bilateral and radial symmetry.

The golden spiral can be detached from the canvas, dragged onto any feature, scaled from 25 to 250 percent and rotated freely.

Color, line width and opacity are adjustable so the overlay stays visible on any photo.

Outline studio

One slider controls the outline strength, and thresholds, blur and noise cleanup are set automatically behind it.

The engine picks a soft or hard edge algorithm based on your photo’s measured contrast.

Compare & iterate

Upload your drawing next to the reference and check it with nine modes: side by side, mirror, squint blur, difference, a neon heatmap, multiply, screen, outline and a split wipe.

Up to 20 draggable ruler lines mark alignments across both images.

One click sends the comparison result back into the grid maker, with no re-upload.

What Is the Grid Method?

The grid method is a drawing technique in which you place a grid over a reference image and copy what you see one cell at a time. Instead of judging a whole face or landscape at once, you compare short lines and simple shapes inside each square, which is far easier for your eye to measure. Artists have worked this way for centuries: Albrecht Dürer published instructions for grid devices in 1525, and the method is still taught in art schools today.

It is not tracing. You draw every line yourself; the grid only gives you fixed reference points to check your proportions against. Most beginners see a clear difference in their first gridded drawing.

Learn takes the method apart in three areas: the grid method, its history from Alberti's veil and the arithmetic of cell size; perspective drawing, one, two and three point with a construction you can drag; and composition, the rule of thirds and the golden ratio laid live over Hokusai's Great Wave. For buildings and rooms the perspective grid lays converging lines over your photo instead of squares.

Who Draws With Grids?

  • Beginners: proportions are the hardest part of learning to draw. The grid takes the guessing out of them.
  • Portrait artists: likeness lives in millimeters. See how they use grids on our portrait artists page.
  • Digital artists: export the PNG and grid your canvas in Procreate or Photoshop.
  • Teachers: the grid worksheet maker prints blank grids with coordinates on Letter and A4, as a class set in one PDF; the page for art teachers has a 45-minute lesson built on it, and printable grids cover the rest.

Frequently Asked Questions

What is a grid maker?
A grid maker lays a measured grid over a reference image so you can copy it cell by cell instead of judging the whole picture at once. You set how large a cell is, move the grid over the subject, and export the gridded reference to print or to keep beside you on a tablet. It is aimed at the part of a drawing that is hardest to repair later: the proportions.
How do I grid a picture on the computer?
Drop the picture into the pad at the top of this page and set the cell size in the grid settings. Drag the grid with the mouse, or nudge the photo under it with the arrow keys, until the lines fall between the features instead of across them, and switch on coordinates if you want every cell to carry an address like B4. Save the result as a PNG or as a PDF when it sits where you want it.
How do I make a drawing grid that matches my paper?
Switch to Grid on Canvas mode and pick the sheet you are drawing on: 18 presets in cm, from DIN A5 up to A0, and 18 in inches, from Letter to Arch C, plus any size you type in. The photo is fitted into that canvas, so the cell size you enter is the size on the paper and not on the screen. Rule the same cells on your sheet and every cell of the export has a twin in front of you.
Why do artists draw with a grid?
Because the eye is bad at judging large proportions and good at comparing short distances. A grid breaks a complex subject into small squares where errors are easy to see, so proportions come out right the first time instead of after repeated corrections.
Can I set the cell size in centimeters or inches?
Yes. The cell size is a real measurement from 0.1 to 100 in the unit you choose, not a count of squares, so a 2.5 cm cell on the export is a 2.5 cm cell on your paper. A 1:1 transfer and a scaled enlargement then become the same job: keep the number of cells, change the cell size.
How do I print the gridded reference at the right size?
Export as PDF. The page is laid out for A4, A3, Letter or Legal with print margins and carries the cell size you set, so print one sheet, measure a cell with a ruler and only then commit good paper. Anything wider than one sheet goes through poster print, which tiles the reference across A0 to A5, Letter, Legal or Tabloid with cut lines and glue strips.
What kind of reference photo works best?
Sharp photos with clear contrast, at least 300 by 300 pixels; JPG, PNG and WebP up to 20 MB are accepted. For portraits, choose a photo where the light creates visible shadow shapes, because those shapes are what you will draw, cell by cell. A picture that is soft on screen stays soft under a grid, and the DPI readout warns you before you print from it.
Is GridMyPic the same as "grid my pic"?
Yes. GridMyPic is the tool people mean when they search for grid my pic or grid my photo. The name is written as one word; the tool is this page.
