What you need
Instructions
- 1
Step 1
Pick a simple picture to copy and place it flat on one sheet of paper.
- 2
Step 2
Decide whether you want to scale the drawing up or down and choose the size of each square for the reference grid.
- 3
Step 3
Use your ruler and pencil to draw a neat grid of equal squares over the reference picture using the size you chose.
- 4
Step 4
Choose a new square size for your copy grid that is larger to scale up or smaller to scale down and write that new size down.
- 5
Step 5
Draw a grid on the blank sheet using the new square size so the copy grid matches the reference grid in rows and columns.
- 6
Step 6
Label the top row with letters and the left column with numbers on both grids so you can match squares easily.
- 7
Step 7
Look at the top-left square on the reference grid and lightly sketch only what you see inside that square into the matching square on the copy.
- 8
Step 8
Continue copying one square at a time across and down the grid until you have transferred the whole picture.
- 9
Step 9
Compare the full copy to the reference and make small pencil adjustments to any squares that look different.
- 10
Step 10
Erase the grid lines from your copy gently without smudging your drawing.
- 11
Step 11
Trace your final drawing lines with a black pen or darker pencil to make the image neat and clear.
- 12
Step 12
Add color to your drawing with your colouring materials if you like.
- 13
Step 13
Take a photo and share your finished scaled drawing on DIY.org
Fun facts
How do I teach my child to scale a drawing using a grid?
To scale a drawing with a grid, place a grid of equal-size squares over the original image (lightly draw or use tracing paper). Draw a larger or smaller grid on blank paper that matches the desired scale (for example, each original square = two target squares for 2×). Label rows and columns, then copy the content of each square into the corresponding square on the new grid, working square-by-square. Use light pencil, check proportions, and erase guidelines when finished.
What materials do I need to scale a drawing with a grid?
You'll need the original image, two sheets of paper (or tracing paper and a blank sheet), a ruler, a pencil, eraser, fine-tip pen or marker for final lines, colored pencils or crayons, and optionally graph paper or a printed grid. For a larger scale, use a larger sheet or poster board. Masking tape helps hold papers steady. A calculator is optional for precise scaling ratios.
What ages is scaling a drawing with a grid suitable for?
This activity suits children roughly ages 6–12, but can be adapted. Younger kids (5–7) can copy simple images with a 1:1 or 2:1 grid with close adult help to teach matching shapes. Ages 8–12 can handle more precise measurement, different scale factors, and more detailed drawings independently. Teenagers can use grids for complex studies, perspective practice, or transfer to larger canvases.
What are the benefits of teaching kids to scale drawings using a grid?
Using a grid to scale drawings strengthens observation, measurement, and proportional reasoning. It builds fine motor skills, patience, and attention to detail while linking art with basic math concepts. Children learn to break complex images into manageable parts, improving confidence and problem-solving. It's also a gentle introduction to scaling and geometry, and can be adapted for collaborative projects or to explore creative variations like changing color or turning scaled grids into patter

What can we use if we don't have a ruler or graph paper for making the reference or copy grid?
Use a straight-edged book, a cereal box cut to a straight edge, or a folded piece of cardboard as a ruler and substitute store-bought graph paper by measuring equal squares with a coin or stamp and marking them lightly in Step 3.
My copied squares look stretched or the picture doesn't match — what should I check or redo?
Check that your chosen square sizes for the reference and copy grids produce the same number of rows and columns, recount and erase any mismeasured grid lines, relabel the letters and numbers, and redraw the blank-sheet grid with your ruler before continuing Step 7.
How can I change the activity for younger children or make it more challenging for older kids?
For younger kids use much larger square sizes, pre-draw both grids and let them sketch with a thick pencil one square at a time, while older kids can use smaller squares, fractional scaling, or graph paper and finish by tracing final drawing lines with a black pen as in Step 11.
What are simple ways to extend or personalize the scaled drawing after finishing it?
After erasing the grid and tracing your final lines with a black pen in Step 11, personalize the piece by adding color, mixed media textures, a background scene, making a series of scaled versions, and then take a photo to share on DIY.org as in the last step.
