Measurement Worksheets
Updated October 2026 · 16 free printables
Free measurement worksheets for kindergarten to 3rd grade, from comparing which crayon is longer and which tree is tallest to measuring with cubes and paper clips, reading inch and centimeter rulers, drawing lines of a given length, estimating before measuring, inches and feet, length word problems, cups, pints, quarts and gallons, measuring jugs in liters and milliliters, and reading a ruler to the nearest half inch.
Every page uses a different kind of exercise, so the set grows with your child instead of repeating one format. The rulers are drawn to scale: print the PDF at 100% (actual size) and the pencils, snakes and bug trails really measure the lengths on the answer key, which is page 2 of every PDF.

Tips for measurement worksheets
- Before using a ruler, check that the end of the object sits exactly on the 0 line.
- Say the unit with every answer: 4 is not finished, 4 inches is.
- For capacity pages, look at the line on top of the liquid, not at the bottom of the container.
Fun math facts
- The US foot is exactly 0.3048 meters, a value fixed by international agreement in 1959.
- A US gallon holds 128 fluid ounces, which is 16 cups or a little under 3.8 liters.
- In 1999 a Mars orbiter was lost partly because one team used pounds and another used metric units.
Fun ways to use your printables
- Measure the family's shoes with paper clips, then with a ruler, and see which way gives bigger numbers.

Frequently asked questions
Why do the rulers need to print at 100%?
The inch and centimeter rulers are drawn at true size. If your printer shrinks the page to fit, a 3-inch pencil will measure a little less than 3 inches with a real ruler. Choose 'Actual size' or 100% in the print dialog; the worksheets still work with the printed rulers either way.
What is a nonstandard unit?
Any object used over and over to measure, such as paper clips, cubes or hand spans. Kindergarten and 1st grade start with these before moving to inches and centimeters, because counting equal units is the big idea behind every ruler.
How do you teach a child to read a ruler?
Start with whole inches: line the object up with 0, then read the number where it ends. Next show that the middle line between two numbers is a half, so an object that ends there is 2 and a half inches. The half-inch worksheet practices exactly that step.
What measurement skills come in each grade?
Kindergarten compares lengths, heights and capacity. 1st grade orders objects and measures with units. 2nd grade uses inch and centimeter rulers, estimates and solves length word problems. 3rd grade measures to the half inch and works with liters and other capacity units.
