What makes isometric different

Isometric drawing shows an object from a corner, with its three main edges at equal angles. Vertical edges stay vertical, and the other two sets of edges run at 30 degrees to the horizontal. The triangular grid on this paper already follows those directions, so you only need to trace along it.

Unlike perspective drawing, lines do not shrink into the distance. A cube's edges are all the same length on the page, which makes isometric ideal for technical sketches where measurements matter.

Drawing your first cube

1. Pick a point and draw a vertical line three grid units long.
2. From the top of that line, draw three units up to the left and three units up to the right along the sloping grid lines.
3. Draw vertical lines down from each end, then join the bottoms back to the start point.
4. Close the top face with two more sloping lines. Shade one side face darker to make it look solid.

3D shapes for maths

Isometric paper is the standard way to draw solids made from cubes in primary and secondary maths. Children build a shape from interlocking cubes, then draw it so that every cube shows three faces. It is also used for plans and elevations: draw the solid in isometric, then draw the view from the front, the side and above on square paper beside it. Counting the cubes in a drawing is a quick way to introduce volume, and drawing a cuboid with sides of 2, 3 and 4 units shows clearly why its volume is 24 cubes.

Design and technology sketches

In design and technology, isometric sketches show a product idea in three dimensions without the extra work of perspective. Start with a crate: a box that encloses the whole object. Then cut away and add details such as handles, rounded edges and buttons. Because equal lengths stay equal, you can mark real measurements along the grid, which makes the sketch useful for planning how a part will be made.

Pixel-style and game-level art

Many retro-style video games use an isometric view for towns, dungeons and puzzle levels. On paper, treat each diamond made of two triangles as one floor tile. Colour tiles for grass, water and paths, then add walls one tile high and raise blocks for steps. It is a good way to plan a level layout or a board game before building it digitally.

Room and furniture layouts

A floor plan shows what fits but not how a room will feel. An isometric sketch adds height, so you can see whether a tall bookcase blocks a window or a bunk bed fits under a sloping ceiling. Choose a scale, such as one grid unit to 25 cm, draw the floor and two walls, then add furniture as simple boxes before refining.

Grid size and printing

The 10 mm grid is easier for children and for first attempts, because each triangle is large enough to count comfortably. The 6 mm grid suits more detailed objects. Print at 100% so that the angles and spacing stay true.
