Pie chart maker
Type or paste your categories and amounts. Percentages, slice angles and the chart update as you type — download it as a PNG for slides in one click.
One slice per line: a label, then a number. Tabs (from Excel/Sheets), commas or spaces all work. Percentages are worked out for you.

How to make a pie chart
- Type one slice per line — a label, then its amount (or paste two columns from Excel or Google Sheets).
- Check the slice maths table: every share and angle is calculated from the total.
- Choose % or value labels, order slices largest-first, and pick a colour set.
- Download PNG (2× resolution), SVG, or copy a share link.
How a number becomes a slice
Drag the amounts. Each slice’s angle is its share of the total × 360°.
When a pie chart is the right choice
A pie chart answers one question: how is one whole split up? Use it when the slices add up to a meaningful total (a budget, a survey where each person picked one answer, market share) and you have roughly two to six categories. Beyond that, slices get too thin to compare and a sorted bar graph is easier to read.
People judge angles and areas less precisely than lengths — a finding from William Cleveland and Robert McGill’s 1984 study of graphical perception. So if the exact difference between two similar slices matters, label the percentages (this tool does by default) or switch to bars.
How the percentages are calculated
Each slice’s share is its value divided by the total of all slices, times 100. Its angle is that share of 360°. A £850 rent out of a £2,000 budget is 850 ÷ 2,000 = 42.5%, and 0.425 × 360 = 153°. You can enter raw amounts or percentages — if your percentages don’t add to 100, the tool scales them so they do, which is worth checking.
Tips for a clearer pie chart
- Order slices from largest to smallest, starting at 12 o’clock (use “Largest first”).
- Group tiny categories into “Other”.
- Skip 3D and exploded slices — they distort the angles.
- Need a total in the middle? Use the donut chart maker.
Questions
Is this pie chart maker free?
Yes. There is no signup, watermark or download limit. Charts are drawn in your browser.
Can I enter percentages instead of numbers?
Yes. Enter the percentages as the values. If they add up to 100 the chart shows them exactly; if not, each slice is shown as its share of whatever they add up to.
How do I make a pie chart from Excel or Google Sheets data?
Select the label column and the value column in your spreadsheet, copy, and paste into the data box. Tabs between columns are detected automatically.
How many slices can a pie chart have?
The tool will draw as many as you enter, but more than six or seven slices become hard to read. Combine the smallest into an “Other” slice or use a bar graph.
How do I calculate the angle for each slice?
Divide the slice value by the total and multiply by 360. A slice worth 25% of the total is 0.25 × 360 = 90°. The slice maths table under the chart shows every angle.
Can I import a CSV file?
Yes. Click “Import CSV” above the data box and choose a .csv or .txt file. It is read in your browser and never uploaded.
Can a pie chart show negative numbers?
No — a slice can’t have a negative size, so zero and negative values are left out. Use a bar graph for data that goes below zero.
