Pie Chart Maker

Add labels and numbers. We’ll do the percentages and draw the pie as you type.

Chart title

Paste rows

One row per line, label then number. Pasting replaces the table.

Data table and alt text

Label	Value	Percent
Rent	1,200	60.0%
Food	600	30.0%
Fun	200	10.0%

Alt text: Where the money goes. Pie chart with 3 slices. Largest: Rent at 60% (1,200 of 2,000). Then Food 30%, Fun 10%.

Add labels and numbers. We’ll do the percentages and draw the pie as you type. Type rows into the table or paste a list straight from a spreadsheet — `Rent, 1,200` works exactly as written, thousands comma and all. The numbers don’t have to add up to 100: give us raw amounts and we work out each slice’s share of the total. Switch to a donut if you want the total in the middle, pick your own color for any slice, and download the chart as a PNG for slides or an SVG for design tools. Most pie chart makers want an account, a template and an editor before you see a single slice. This is just the pie.

How to use

1
Type a label and a number in each row of the table, or paste your rows into the paste box — one per line, like Rent, 1,200. Pasting replaces the table.
2
Watch the pie redraw as you type. Slices start at 12 o’clock and go clockwise in the order you listed them.
3
Set a chart title, switch between Pie and Donut, and choose whether slices show the percent, the value or both.
4
Click a row’s color swatch to change that slice’s color.
5
Click Download PNG, Download SVG or Copy chart. The data table and ready-made alt text are under the chart if you need them.

Frequently asked questions

Do my numbers need to add up to 100?

No. Type the raw amounts — dollars, votes, hours, anything — and we divide each one by the total to get its share. Rent 1,200, Food 600 and Fun 200 come out as 60%, 30% and 10%. If your numbers already are percentages, that works too: 45% reads as 45.

Why do the percentages always add up to exactly 100.0%?

Rounding each slice on its own can leave you at 99.9% or 100.1%. Three equal slices are 33.333…% each, and rounding all three gives 99.9%. We use largest-remainder rounding instead: round everything down to one decimal, then give the leftover tenths to the slices that lost the most in rounding. Three equal slices become 33.4%, 33.3% and 33.3%, which is what a teacher checking your work expects to see. One catch: a very thin slice, like 1 next to 250,000, can round down to nothing. It is still there, so it reads <0.1% instead of a misleading 0.0%.

How do I type a number like 1,200?

Just as you would anywhere else. The value is the last number on the line, and a comma counts as a thousands separator when exactly three digits follow it. So Rent, 1,200 is 1,200 and Salt, pepper, 5 is a slice called “Salt, pepper” worth 5. A line like Week 1,40 is ambiguous: it could be Week = 1.40, or a slice called “Week 1” worth 40. We ask instead of guessing, and either answer works when you type it back — Week 1.40 for the decimal, or Week 1, 40 (a comma and a space) to keep the 1 in the label. If the first line of a paste is a header like Category, Amount, we skip it and tell you.

What happens with zero or negative values?

A zero stays in the legend at 0.0% but draws no slice, so it’s obvious the category exists and is empty. A pie can’t show a negative amount — there’s no such thing as a slice smaller than nothing — so negative rows are marked and left out while the rest of the chart still draws. If you need to show gains and losses, a bar graph is the right chart.

When should I use a pie chart instead of a bar graph?

Use a pie when the parts make up one whole and the question is “how big is each share?” — a budget, survey answers, time in a day. Keep it to a handful of slices; past about a dozen, small slices get hard to tell apart and we’ll say so. If you’re comparing amounts that don’t add up to a whole, or comparing several series side by side, use a bar graph instead.

Why don’t small slices have a label on the chart?

A slice under 3% is too thin to hold readable text, and a label crammed onto it overlaps its neighbors. Those slices still get their full name, value and percent in the legend, which lists every row.

What’s the difference between Download PNG, Download SVG and Copy chart?

Download PNG saves an image at twice the on-screen size, sharp enough for slides and documents. Download SVG saves the vector original, which stays crisp at any size and opens in Figma, Illustrator or a browser. Copy chart puts the PNG on your clipboard so you can paste it straight into a doc or a chat; if your browser won’t copy images, it copies the SVG code instead.

Is my data uploaded anywhere?

No. The chart is drawn in your browser from the numbers on the page. Nothing is sent, stored or logged, and closing the tab clears it.

What the Pie Chart Maker produces

The Pie Chart Maker turns a short list of labels and numbers into a pie chart that shows each one's share of the whole. You type rows, the pie redraws as you type, and you download it as a PNG or an SVG. There is no Generate button and nothing to set up first. A sample chart is already on the page when it loads.

That sample is a household budget, and it shows the whole idea in three rows:

Rent, 1,200 · Food, 600 · Fun, 200

Total 2,000 → Rent 60.0% · Food 30.0% · Fun 10.0%

You give it raw amounts. It does the division. The finished chart carries its title, every slice, and a legend that lists each row with its value and its percentage. That matters more than it sounds. The chart usually ends up on a projected slide in front of people who never saw your numbers. The picture has to explain itself.

It draws a classic pie or a donut, labels slices with the percent, the value or both, and lets you pick any slice's color. The chart is built in your browser from the numbers on the page. Nothing gets uploaded.

Why a pie chart maker beats drawing one — and beats the big editors

You can draw a pie chart by hand. You need a compass, a protractor, and a calculator for the angles. For a class survey with five answers that's twenty minutes of careful work, and one wrong division throws off every slice after it. A pie chart maker does the arithmetic exactly and draws the arcs to the degree.

The other common route is a big design or office suite. That's where the pattern gets tiresome. A pie chart is a list of numbers, and most chart tools treat it like a design project. First comes a sign-in wall. Then a template gallery. Then a full editor with forty panels, a free trial that asks for a card, and a "Pro" badge on the export button. Some bury the chart three menus deep inside a subscription you pay for every month, whether you make one chart a year or fifty.

This one is just the pie. Open the page, paste your rows, take the image, leave. It works the same whether you're a sixth-grader finishing a survey project the night before it's due, a teacher building a worksheet, a freelancer showing a client where the budget went, or someone at a large company who needs one clean chart for Monday's deck.

It's also the full tool. The rounding, the paste handling and the export are the same for everyone. There's no cut-down version waiting for an upgrade.

How a pie chart is calculated

Every pie chart runs on one idea. Each slice's share is its value divided by the total. Its angle is that share times 360 degrees.

Take a class survey. 24 students name their favorite fruit. The tally comes back as Apples 7, Bananas 5, Grapes 6, Oranges 4 and Mango 2. Here is what the Pie Chart Maker works out:

Fruit	Votes	Share (votes ÷ 24)	Angle (share × 360°)	Label on the chart
Apples	7	0.2917	105°	29.2%
Bananas	5	0.2083	75°	20.8%
Grapes	6	0.25	90°	25.0%
Oranges	4	0.1667	60°	16.7%
Mango	2	0.0833	30°	8.3%
Total	24	1	360°	100.0%

The first slice starts at 12 o'clock. The rest follow clockwise in the order you listed them. So Apples runs from 12 o'clock to 105°, Bananas from 105° to 180°, and so on around the circle. If you want the biggest slice first, list it first.

If your homework asks you to show the angle column, this table is the working. Divide, multiply by 360, check the angles add up to 360°. The tool's chart is the answer key.

Why the percentages always add to 100.0%

Rounding each slice on its own can leave you at 99.9% or 100.1%, and a teacher will spot it. Try a school day: Sleep 8, School 7, Homework 2, Sports 2, Screens 3, Other 2. That's 24 hours. Round each slice separately and you get 33.3 + 29.2 + 8.3 + 8.3 + 12.5 + 8.3 = 99.9%.

The Pie Chart Maker uses largest-remainder rounding instead. Sleep's true share is 33.33…%, which lost the most in rounding, so it gets the spare tenth and reads 33.4%. The labels now add to exactly 100.0%. The angles are never rounded. Sleep is still exactly 120°.

How to make a pie chart from a spreadsheet

Most people's numbers already live in a spreadsheet or a notebook tally. You don't need to retype them.

Select the two columns in your spreadsheet — labels and numbers — and copy them.
Paste into the Paste rows box under the table. Pasting replaces the table.
Check the chart. Fix any row marked in red.
Set a title, then click Download PNG.

The parser reads a pasted line the way you meant it, not the way a naive split would:

Column breaks come first. A tab, a comma followed by a space, or two or more spaces separates the label from the number. The value is the last cell on the line, so Salt, pepper, 5 becomes a slice called "Salt, pepper" worth 5.
Header rows are skipped. If the first pasted line is something like Category / Amount and more rows follow, it's dropped with the note "We skipped the first row. It looked like a header."
Currency signs and a trailing % are stripped. Rent / $1,200 reads as 1,200. Yes, 45% reads as 45.
Extra columns are ignored. Paste January and February side by side and the chart uses the first number column, with a note saying so. A pie shows one set of numbers.
Years work as labels. 2021,120 is the label 2021 with the value 120, not a strange decimal.

Numbers that are already percentages work fine. Type Yes, 45% and No, 55% and you get 45.0% and 55.0%. They don't have to add to 100, though — raw counts, dollars or hours all work, and the tool finds the shares.

Customizing the chart

The controls sit right under the chart. There are only a few, and each one changes something you can see.

Option	Default	Choices	What it does
Chart title	Where the money goes	Up to 120 characters	Printed at the top of the chart and saved in both exports
Chart style	Pie	Pie / Donut	Donut cuts a hole 55% of the pie's width and writes the total in it
Slice labels	Percent	Percent / Value / Both	What each slice says: `60.0%`, `1,200`, or `1,200 (60.0%)`
Slice color	12-color palette, cycling by row	Any color, per row	Click a row's swatch to recolor that slice and its legend entry
Rows	The 3 sample rows	Up to 50 drawn	Add row, the × button, or Clear all

For a slide, the defaults are usually right: Pie with percent labels, because the audience wants shares. Switch to Both when the amounts matter too, like a budget where "60%" alone hides that rent is 1,200. Pick the donut when the total is the headline. The sample budget's donut reads Total 2,000 in the center.

Under the chart, the Data table and alt text panel lists every row with its value and percent. It also holds a one-line description you can paste as alt text for a screen reader: "Pie chart with 3 slices. Largest: Rent at 60% (1,200 of 2,000). Then Food 30%, Fun 10%."

Download PNG saves an image at twice the on-screen size. The sample chart comes out 960 pixels wide, sharp on a projector. Download SVG saves the vector version, which stays crisp at any size. Copy chart puts the image on your clipboard for pasting straight into a doc or a chat.

Common mistakes, and when a pie chart is the wrong chart

If your chart isn't drawing, or a row went red, here's what to check first. The tool never guesses at a number that could mean two things. It asks, and its advice works when you type it back.

A comma that could be a decimal

Week 1,40 could be Week = 1.40, or a slice called "Week 1" worth 40. The tool stops and asks: "Is that 1.40? Use a dot for decimals — or, if 1 is part of the label, put a comma and a space before 40." Type Week 1.40 for the decimal. Type Week 1, 40 to keep the 1 in the label.

A space inside a number

Team 1 250 gets the same treatment: is that 1,250, or "Team 1" worth 250? Write Team 1,250 for the first, Team 1, 250 for the second.

Negatives and zeros

A pie can't hold a negative slice. In Sales 500, Refunds -80, Fees 100, the refund row is marked and left out, and the other two draw at 83.3% and 16.7%. A zero stays in the legend at 0.0% and draws nothing. If every row is zero, there's no pie to draw, and the tool says so.

Too many slices

From 13 rows on, the tool adds a note: "That's a lot of slices. It works, but small ones get hard to read." It draws up to 50. Slices under 3% get no label on the chart itself, only in the legend.

A pie chart answers one question: how big is each part of one whole? If your numbers don't add up to a meaningful whole — test scores for five students, sales by year — or you want to compare two groups side by side, use the bar graph maker instead. Bars are easier to compare by eye than angles.

Related tools

Charts rarely travel alone. If you're comparing amounts across categories or over time, the Bar Graph Maker takes the same kind of list and draws bars. To check one share by hand — what percent is 7 of 24? — the percentage calculator does it in a line, and percent to fraction turns 25% into ¼ for a math worksheet. Need a mean for the same survey? The average calculator handles it. And if the default colors clash with your slides, the color palette generator gives you a matching set of hex codes to drop into each row's swatch.

Frequently asked questions

How do I work out the angle of each slice in a pie chart?

Divide the slice's value by the total, then multiply by 360. In a survey of 24 students where 7 picked apples, the apple slice is 7 ÷ 24 × 360 = 105°. The Pie Chart Maker draws with those exact angles, so your hand-drawn version should match it slice for slice.

What order are the slices drawn in?

The order you list them. The first row starts at 12 o'clock and the rest go clockwise. The tool never re-sorts your rows, so if you want the largest slice first, or an "Other" slice last, put it there in the table.

How many slices can a pie chart have?

This tool draws up to 50. If you paste more, it draws the first 50 and leaves the rest out. A good pie usually has two to six slices, though. Past a dozen, thin slices start to look alike, which is why the tool flags 13 or more.

Can I make a donut chart instead?

Yes. Switch the style toggle from Pie to Donut. The slices stay the same size and the center shows the total, so the sample budget reads "Total 2,000" in the middle. Donuts work well when the total is part of the story.

Does it make 3D or exploded pie charts?

No, on purpose. Tilting a pie into 3D makes the front slices look bigger than the back ones, so the picture lies about the numbers. Pulling slices out adds nothing a color change can't do. Flat slices read true.

Can I use the chart in a school project or a work report?

Yes. The chart is made from your numbers and it's yours to use anywhere, with no watermark and no credit line. The PNG and SVG carry the title and a full legend, so the image makes sense on a slide without the page behind it.
