Math
Range Calculator
Find the spread of a list of numbers, from the smallest to the largest value.
This result shows how far apart the smallest and largest numbers are, so a larger range means the values are more spread out.
Formula
Range = largest value − smallest value.
How it works
Type numbers separated by commas. The calculator finds the smallest and largest values and subtracts to give the spread.
Worked example
For example, for the numbers 4, 8, 15, 16, 23 and 42, the smallest value is 4 and the largest value is 42, so the range is 42 − 4 = 38.
