Step by Step Triangle Ruler Drawing Instructions

Step 1 – Start with Two Lines for the Triangle Base

Step 1 of how to draw a triangle ruler – Sketching a long diagonal line and a short horizontal line to start the triangle base.

Begin by drawing one long diagonal line going up to the right, then add a shorter horizontal line starting from its bottom. It’s like the letter “L” tipped on its side!

Step 2 – Complete the Triangle Shape

Step 2 of drawing a triangle ruler – Completing the basic outline by adding the third line to form a closed right triangle shape.

Now draw the third line to close the shape into a triangle. It should connect the top of the diagonal line to the end of the short base. You’ve now got a perfect right triangle!

Step 3 – Add the Inner Triangle Hole

Step 3 of sketching a triangle ruler for beginners – Drawing a smaller inner triangle to create the ruler's hollow center.

Let’s draw the hollow part inside! Inside the big triangle, sketch a smaller triangle that mimics the shape and angles. This makes it look like a real plastic triangle ruler.

Step 4 – Draw the Measurement Marks

Step 4 of step-by-step triangle ruler sketch – Adding small, evenly spaced tick marks along the longest side for measurements.

Time to turn it into a ruler! Along the longest side, draw a bunch of small lines. These are the measuring tick marks—keep them evenly spaced like on a real ruler.

Step 5 – Add the Number Labels

Step 5 of easy triangle ruler drawing steps – Writing small numbers (1-7) beside the measurement marks to label them.

Let’s number those lines! Write tiny numbers next to the measurement marks. 1 through 7 is a fun range for our cartoon ruler!

Step 6 – Give Your Ruler a Cute Face

Step 6 of simple triangle ruler drawing tutorial – Adding a cute face with two circle eyes and a smiling mouth to the ruler.

Now for the fun part—add a cute face! Draw two little circles for eyes and a smiling mouth near the bottom of the triangle. Now your ruler has personality!
