Overview
What is a waffle chart?
A waffle chart turns a part-to-whole split into a 10×10 grid of 100 squares, each one worth exactly one percentage point. A category holding 38% of the total claims 38 squares, filled in one solid, countable block — not a wedge you have to judge by eye. It does the same job as a pie or donut chart, but reads more literally: because every square is an identical unit, a viewer can verify a share by counting rather than estimating an angle or an arc length.
That literalness is why the format tests so well for accuracy, and why it holds up with more categories than a pie chart can. A 3% slice on a pie is a sliver nobody can read; a 3% share on a waffle is still three whole, visible squares. It's also inherently square, which makes it a natural fit for a LinkedIn post or an Instagram tile without any cropping.
The trade-off is precision at the edges: a waffle chart rounds every share to the nearest whole square, so two categories at 24.6% and 25.4% both render as roughly a quarter of the grid. When the exact decimal matters more than the visual proportion, a table or a labelled bar chart is the more honest choice.
How it works
How a waffle chart works
Each category's share of the total is converted into a whole number of squares out of 100, using a rounding method that guarantees the squares always add up to exactly 100 even after rounding every category individually.
Reochart fills the grid in category order, popping each square in one by one so the shape of the split builds in front of the viewer instead of appearing all at once. A legend below names each category and its share.

Good fit
When to use a waffle chart
- ✓A survey result as a share of respondents
- ✓A budget or spend split by category
- ✓Any "X% of" stat built for a social post
Reach for something else
When not to use a waffle chart
- ✕You have more than about 8 categories, individual squares start blending together across colours and a bar chart reads more clearly.
- ✕The exact decimal matters more than the rough proportion, rounding to the nearest square hides fine differences a table or labelled bar wouldn't.
- ✕You're showing change over time rather than a single split, a line or area chart carries a trend a static grid can't.
- ✕Categories vary wildly in count, like 2 vs 200 respondents, the smaller one may round to zero squares and disappear entirely.
Compare
Waffle chart vs other charts
Waffle chart vs the other part-to-whole formats.
| Chart type | Best for | Avoid when |
|---|---|---|
| Waffle | A literal, countable percentage split, great for social | Precision to the decimal matters, or you have 8+ categories |
| Pie / donut | The most familiar shape, good for 3-6 slices | Slices are close in size or there are many of them |
| Pictogram | A human, icon-based version of the same idea | You want a strict, uniform grid rather than icon rows |
| Bar chart | Exact values across many categories | The point IS the visual proportion, not the precise number |
Your data
What data you need
One row per category: a label and a value. Values don't need to add up to 100 — Reochart normalises them into shares automatically. 3 to 6 categories reads best.
| Label | Value |
|---|---|
| Word of mouth | 38 |
| Social posts | 27 |
| Search | 19 |
| Paid ads | 10 |

Best practices
Get it right
- ✓Keep it to 3-6 categories so every square stays easy to attribute to its colour.
- ✓Order categories largest to smallest so the biggest block reads first.
- ✓Use a square (1:1) export format — it's a natural fit for the grid's own shape.
- ✓Let the legend carry the exact percentage; the grid carries the feeling of scale.
- ✕Cram in 10+ categories, tiny 1-2 square slivers get lost in the grid.
- ✕Rely on it when a viewer needs to read an exact number, not just a rough share.
- ✕Use near-identical colours for adjacent categories, the grid depends on colour contrast to separate them.
- ✕Force it into a wide landscape format, the grid wants to stay roughly square.
Watch out
Common mistakes to avoid
Past 8 categories, several 1-2 square slivers compete for attention and the grid stops reading as a clean split. Group the smallest into "Other."
A waffle chart rounds to the nearest whole square (1% of the grid). If the story hinges on 24.6% vs 25.4%, use a table instead.
Two similarly-coloured categories next to each other in the grid are hard to tell apart square by square. Pick a theme with clearly distinct hues.
A waffle chart is a single snapshot. If the real story is how a share changed over several periods, a stacked bar or line chart shows that; a waffle chart can't.

FAQ
Frequently asked questions
What is a waffle chart?
A waffle chart is a square grid, usually 10 by 10, used to show a part-to-whole split. Each of the 100 squares is worth exactly one percentage point, so a category holding 38% of the total claims 38 squares, filled in one solid block. It does the same job as a pie or donut chart, showing how a whole breaks into parts, but reads more literally: because every square is an identical, countable unit, a viewer can verify a share by counting rather than by judging an angle or an arc length, which is a large part of why the format tests well for accuracy in isolation. It also tolerates more categories gracefully than a pie chart before the smaller slices become unreadable slivers, since even a 3% category still gets three whole, visible squares.
Is this the same as a percentage grid or unit chart?
Yes — "waffle chart", "percentage grid" and "square pie chart" all describe the same 10×10, 100-square format. Reochart's generator produces the same animated result under any of those names.
How many categories can I show?
Up to eight. Past that, individual squares start to blur together across categories, and a bar or donut chart reads more clearly.
Do the percentages have to add up to 100?
No — Reochart normalises your values automatically, so raw counts (signups, respondents, dollars) work directly without you calculating shares first.
Waffle chart or pictogram, which should I use?
Both turn a share into countable units. A waffle chart's uniform grid feels more precise and data-driven; a pictogram's icon rows feel warmer and more human. Pick based on tone, the underlying math is the same.
Can I make it animated?
Yes. Charts animate by default, and you can export the animation as an MP4 or GIF, or grab a static PNG or SVG if you prefer.
Can I export as SVG?
Yes. Pro exports a crisp, scalable SVG vector, alongside MP4, GIF and PNG. Every export renders at 1080p.
Is Reochart free?
Yes. The free plan lets you make every chart type except the animated bar chart race, and export an animated MP4 with a small watermark, no card needed. Pro adds the bar chart race, removes the watermark, and adds GIF and SVG, your brand colours and logo, longer videos and CSV import.
