Are the objects really that long?

Yes, when you print at 100% scale (actual size). A 7 cm pencil on the sheet measures 7 cm with any ruler, so children can check with a real one.

Inches or centimeters?

Both. Choose inches or centimeters; the ruler and the answers change to match.

What is “use your own ruler”?

The objects are printed without a ruler, so children line up a classroom ruler themselves, which is the real skill: starting at zero, not at the end of the ruler.

Is there an answer key?

Yes, with every length written in, at the end of the PDF.

Measuring length worksheets

Pencils, crayons and worms drawn real size. Measure each with the printed ruler, or with your own, and write its length.

The most common mistake

Children often start measuring from the end of the ruler, or from 1. On the printed-ruler sheets every object starts exactly at zero; on the “use your own” sheets they have to line it up themselves.

Real size

Every sheet is drawn to scale, so the objects are as long on paper as their measurements say. That makes it easy to check an answer with a real ruler.
