About the Measuring Length Worksheet Generator

The Measuring Length worksheet generator creates free, printable measurement worksheets you can customize, preview, and download in seconds. Adjust the number range, layout, and difficulty to fit your child or class; every worksheet is generated fresh and includes a complete answer key on the second page. There are no sign-ups, no watermarks, and no limits on how many you can print.

Recommended for K - 2nd, this generator is part of our Measurement & Maps collection. Measurement worksheets connect counting to the real world: students learn what a unit is, how to line up a ruler, and how to compare and estimate lengths. Measure with cubes, paper clips or real-size rulers, compare and order lengths, estimate, measure two ways and draw lines.

How to use these worksheets

For teachers

Use real rulers when measurement worksheets call for it; relate the printed scale to a physical tool.
Start with paper clips or cubes laid end to end, then move to inches and centimeters.
Check that students line up the end of each object with the 0 on the ruler, not the edge of the ruler.
Ask for an estimate before each measurement, then compare the estimate with the answer.

For parents and at home

Use a real ruler or measuring tape with your child as you complete measurement worksheets.
Measure toys, spoons, and shoes at home and talk about which is longer or shorter.
Guess first, then measure: a good estimate is a skill worth practicing.

Skills your students will practice

Measuring with non-standard units (paper clips, cubes)
Measuring with a ruler in inches and centimeters
Comparing the lengths of objects
Finding how much longer one object is than another

Aligned to Common Core State Standards

The worksheets generated here support the following Common Core math standards:

K.MD.A.1: Name the features of an object that can be measured, such as how long or how heavy it is, including several for one object.
K.MD.A.2: Put two objects side by side to see which is longer, taller, heavier and so on, and describe the difference.
1.MD.A.1: Put three objects in order from longest to shortest, and compare two lengths by checking each against a third object.
1.MD.A.2: Measure an object by lining up equal-size units (like cubes) along it without spaces or overlapping, and give the whole-number count.
2.MD.A.1: Choose a suitable tool, such as a ruler, yardstick, meter stick or tape measure, and use it to measure length.
2.MD.A.2: Measure one object with two different units, such as inches and centimeters, and explain why a smaller unit gives a bigger number.
2.MD.A.3: Make sensible guesses of lengths in inches, feet, centimeters and meters.
2.MD.A.4: Measure two objects and find the difference in their lengths in a standard unit.
2.MD.B.5: Solve story problems about lengths in the same unit, adding or subtracting within 100, with drawings like rulers and equations.
2.MD.D.9: Measure several objects, or one object several times, in whole units and display the results on a line plot.
