How to Create an Isometric Grid in Adobe Illustrator

This is a very quick and easy tutorial for creating an isometric grid in Adobe Illustrator, which you can then either work directly over in Illustrator or print out for freehand sketching.

If you want to skip the tutorial and get working in isometric right away, download these completed grids in PDF format, ready for printing or import into Illustrator or Corel:

1. Create a new document (File > New…). In this case we’re creating a grid we can print out, so we’ll make it letter sized. Set the units to Inches.

Create a new document

2. Draw a vertical line longer than the page. Select the Line tool [press the \ key] and click once (don’t drag) or press Enter. Enter a length of 15 and angle 90 for a 15 inch vertical line.
Draw a line up, longer than you need
3. Move the line to the lower left corner. Using the Selection tool or “black arrow” [V] grab the line by the lower point and drag it to the lower left corner of the page. Your cursor should turn white when you’re over it.
Adjust Keyboard Increment
4. Set the Keyboard Increment to 0.125 in. Open the Preferences panel (File > Preferences > General or Illustrator > Preferences > General, or simply Ctrl/Command K). Type 0.125 for 1/8″ increments. Press OK.

Set Keyboard Increment

5. Duplicate the line horizontally. Hold the Alt/Option key and press the Right arrow key. The line will be duplicated 0.125″, our increment setting, to the right of the original. Keep doing this until the duplicates run well off the page.

Duplicate the line

6. Rotate 60 degrees. Select all the lines (drag a marquee selection using the Selection tool [V] or press Ctrl/Command A). Select the Rotate tool [R] and press Enter. Type 60 for Angle. Hit Copy. Align the end of one of the lines to the top left corner.
Select Rotate tool (R), press Enter, type 60 degrees

8. Reflect. Select the Reflect tool and press Enter. Ensure the Vertical radio button is selected, then press Copy.

Select the Reflect tool, press Enter
9. Check the alignment. The grid should look like this, all identical equilateral triangles.
Check alignment

10. Select everything. Drag a marquee selection with the Selection tool [V] or press Ctrl/Command A. Group all the lines (Object > Group or Ctrl/Command G).

Select all (Ctrl/Command A)
11. Draw a rectangle. Select the rectangle tool [M] and click (don’t drag) on the top left corner. Make the rectangle 8 x 10.5 inches and press OK.
Draw a rectangle
12. Position the rectangle. Press [Down] twice and [Right] twice. This will give us a 1/4″ border on all sides of the rectangle.

Adjust rectange position (press Right twice, Down twice)
13. Select everything. Ctrl/Command A.
Select all (Ctrl/Command A)
14. Create a clipping path. Object > Clipping Path > Make or Ctrl/Command 7. This will hide everything outside of the rectangle.

Object > Clipping Mask > Make (Ctrl/Command 7)
16. Add a title block (optional). Include your logo, a place for a title, your name and the date.
