Random Pie Chart Generator

Press Generate to make a random pie chart with 3 to 8 slices. Each chart comes with five practice questions and an answer key, so it works as a pie chart worksheet. Print it, or open the chart in the pie chart maker to change the numbers.

From our own data: of 13,058 charts downloaded here from January 29 to August 18, 2026, 77.9% had 6 slices or fewer, so the generator starts at 5.

What you can do with a random pie chart

A random pie chart gives you data to practice on without surveying anyone. Teachers use one as a warm-up, a quiz or a differentiated worksheet: three slices for early readers, eight for students who are ready to see where pies get crowded. Students use one to check their own method, because the table shows each slice's percent and angle.

The five questions cover the skills in most pie chart units: find the biggest slice, turn a percent into a count, compare two counts, write a fraction in simplest form, and find an angle. For the method behind the last two, see how to read a pie chart, the circle graph maker for angles, and fraction pie charts.

How the random data is made

The data is made up, not collected. The generator picks the number of categories you asked for from the theme, gives each at least one vote, and spreads the remaining votes at random until they add up to the total. If two slices tie for the largest it tries again, so the most popular choice is always one slice. The total is 20, 25, 50 or 100, which makes each vote worth a whole percent (5, 4, 2 or 1).
