What is a marimekko chart in PowerPoint?
A marimekko chart in PowerPoint is a variable-width stacked column chart used when one slide must show both total category size and internal mix. Microsoft Support’s Office chart list, accessed July 2026, includes column, line, pie, bar, area, scatter, treemap, waterfall, funnel, combo, and map charts, but does not list Marimekko or Mekko as a built-in chart type.
The chart is also called a Mekko chart or mosaic plot. Domo’s 2026 chart guide describes it as a variable-width stacked column chart where width shows each category’s total value, height shows each segment’s percentage share inside that category, and area shows each segment’s absolute contribution to the grand total.
| Visual element | What it means | PowerPoint implication |
|---|---|---|
| Column width | Category total divided by grand total | You must calculate widths before drawing or use an add-in |
| Segment height | Segment value divided by category total | Each column must stack to 100% |
| Rectangle area | Column width multiplied by segment height | Area represents absolute contribution across the whole dataset |
| Column gap | Usually zero or visually minimal | Gaps distort the size comparison between categories |
When should you use a marimekko chart powerpoint slide?
Use a marimekko chart powerpoint slide for a static market, portfolio, channel, or revenue snapshot where total size and share mix are equally important. Domo’s 2026 guidance recommends it for portfolio analysis, market share comparisons, and competitive landscapes, especially with fewer than seven categories.
A good use case is a market-share slide where California, Washington, and Nevada have different total sales, and Bose, Dell, and Apple have different mixes inside each state. FusionCharts’ Marimekko documentation gives this sample: California totals $724,300, Washington totals $533,000, Nevada totals $560,900, and the three-state total is $1,818,200.
| Use it when | Do not use it when |
|---|---|
| You need to compare total category size and internal percentage mix in one slide | You only need to rank categories by one number |
| You have 3 to 7 categories and 2 to 5 segments per category | You have 12 months or 20 products; the chart will become cluttered |
| All values are non-negative and each category can be converted to 100% | The dataset has negative values, because negative widths and stacked shares break the visual logic |
| The slide is a static snapshot, such as 2026 market structure | The slide is a time series; shifting widths make trend comparison harder |
What data do you need for a marimekko chart powerpoint example?
You need a rectangular table of positive values where columns are categories and rows are segments. The FusionCharts Marimekko example uses three states and three electronic brands, giving nine numeric cells that can be turned into widths, heights, and areas for a PowerPoint slide.
| State | Bose sales USD | Dell sales USD | Apple sales USD | State total USD | State width |
|---|---|---|---|---|---|
| California | 335000 | 225100 | 164200 | 724300 | 39.84% |
| Washington | 215000 | 198000 | 120000 | 533000 | 29.31% |
| Nevada | 298000 | 109300 | 153600 | 560900 | 30.85% |
| Total | 848000 | 532400 | 437800 | 1818200 | 100.00% |
| State | Bose height | Dell height | Apple height |
|---|---|---|---|
| California | 46.25% | 31.08% | 22.67% |
| Washington | 40.34% | 37.15% | 22.51% |
| Nevada | 53.31% | 19.49% | 27.38% |
The calculation is mechanical: state width equals state total divided by $1,818,200, and brand height equals brand sales divided by that state’s total. For California, width is 724,300 divided by 1,818,200, or 39.84%; Bose height is 335,000 divided by 724,300, or 46.25%.
How do you build a marimekko chart in PowerPoint manually?
PowerPoint can insert standard charts through Insert > Chart, and Microsoft Support says a worksheet opens so you can replace placeholder data. Because Marimekko is not a built-in Office chart type, the manual PowerPoint method uses calculated rectangles instead of a native chart object.
Manual rectangle method for a 10 inch by 5 inch plot area
- Step 1: Create a blank 16:9 slide and draw a 10 inch wide by 5 inch tall plot area.
- Step 2: Calculate each state width from the sample data: California 39.84%, Washington 29.31%, Nevada 30.85%.
- Step 3: Convert widths to inches: California 3.984 inches, Washington 2.931 inches, Nevada 3.085 inches.
- Step 4: Calculate segment heights inside each state: California is Bose 46.25%, Dell 31.08%, Apple 22.67%; Washington is Bose 40.34%, Dell 37.15%, Apple 22.51%; Nevada is Bose 53.31%, Dell 19.49%, Apple 27.38%.
- Step 5: Convert heights to inches on a 5 inch plot: California Bose 2.313 inches, Dell 1.554 inches, Apple 1.134 inches; repeat the same calculation for Washington and Nevada.
- Step 6: Insert rectangles with no gaps, stack each state to exactly 5 inches, and label each rectangle with brand name plus percent.
- Step 7: Add a bottom axis with state names and state totals: California $724.3K, Washington $533.0K, Nevada $560.9K.
- Step 8: Add a chart title that states the takeaway, for example: Bose is the largest brand overall at $848K, while California is the largest state at $724.3K.
| Formula | Example |
|---|---|
| Category width = category total / grand total | California = 724300 / 1818200 = 39.84% |
| Segment height = segment value / category total | California Bose = 335000 / 724300 = 46.25% |
| Segment area share = segment value / grand total | California Bose = 335000 / 1818200 = 18.42% |
| Rectangle width in inches = plot width x category width | 10 x 39.84% = 3.984 inches |
What is the best way to make a marimekko chart in PowerPoint?
The best method depends on whether you need one static slide, linked Excel data, or repeatable consulting-style chart production. As of July 2026, public guidance from Microsoft, think-cell, empower, Ampler, and Mekko Graphics all points to the same practical fact: Marimekko is not a standard native PowerPoint chart.
| Method | What you get | Best fit | Main tradeoff |
|---|---|---|---|
| Manual PowerPoint rectangles | A fully editable slide shape build | One-off static slide with 3 to 5 categories | Data changes require manual resizing and relabeling |
| Excel workaround copied to PowerPoint | A chart-like object built outside the slide | Users comfortable with Excel formulas and chart hacks | Formatting can be fragile and time-consuming |
| think-cell Mekko | Percent-axis Mekko and units-based Mekko inside PowerPoint | Teams that already use think-cell for business charts | Requires the add-in and its workflow |
| empower or Ampler add-in | PowerPoint ribbon workflows and Excel-linked data options | Enterprise presentation teams with add-in governance | Requires installation and tool access |
| Mekko Graphics | Dedicated charting including Marimekko, Bar Mekko, Waterfall, Gantt, Bubble, Scatter, and more | Analysts who produce many market-structure charts | Another specialized tool in the workflow |
| AnyGen | A generated slide-ready chart, explanation, source table, and deck outline from one prompt | Fast first drafts and editable client-ready slide material | You should still verify the final numbers against your source dataset |
think-cell’s manual describes two Mekko variants: a percent-axis Mekko, also called a 100% cost curve, where variable widths make segment areas proportional to absolute values; and a units-based Mekko, also called a submarine or olympic chart, where both the value axis and datasheet use absolute values.
How do you create a marimekko chart powerpoint deck with AnyGen?
AnyGen helps when the task is not just drawing the Marimekko, but turning the chart into a usable PowerPoint-style story: source table, formulas, chart takeaway, slide titles, annotations, and speaker-ready explanation. Use it for first-draft speed, then check the numbers against the original spreadsheet.
Copy-and-paste prompt
Create a 16:9 PowerPoint-style deck about this marimekko chart. Use columns as states and rows as brands. Data in USD: California Bose 335000, Dell 225100, Apple 164200; Washington Bose 215000, Dell 198000, Apple 120000; Nevada Bose 298000, Dell 109300, Apple 153600. Show width as state total share, height as brand share within state, and area as absolute contribution. Include one chart slide, one calculation slide, one interpretation slide, and one recommendation-free summary slide.
- Step 1: Paste the dataset and specify that the desired chart type is marimekko, not stacked bar or 100% column.
- Step 2: Ask for the width calculation, percent mix calculation, and a validation row that confirms each state totals 100%.
- Step 3: Ask for one takeaway sentence: Bose is the largest brand overall at $848K, and California is the largest state at $724.3K.
- Step 4: Review the generated slide table before presenting, especially rounded percentages such as California width 39.84% and Nevada width 30.85%.
- Step 5: Edit labels for readability; hide any label below 8% if the final slide becomes crowded.
How should you format a marimekko chart powerpoint slide?
Format the slide so viewers read the total-size comparison first and the mix comparison second. In the FusionCharts sample, California should visibly be the widest column at 39.84%, Nevada second at 30.85%, and Washington third at 29.31%.
- Use one color per brand across all states: Bose one color, Dell one color, Apple one color.
- Place state totals under the x-axis: California $724.3K, Washington $533.0K, Nevada $560.9K.
- Use direct labels inside segments when space allows: Bose 46.25% in California, Bose 40.34% in Washington, Bose 53.31% in Nevada.
- Add a small note explaining that width equals state total share and height equals brand share within state.
- Avoid 3D effects, shadows, and large gaps because they distort rectangle area.
- Use a sorted order if your story is about market size; in the sample, sort columns California, Nevada, Washington if ranking strictly by state total.
| Slide element | Recommended wording |
|---|---|
| Title | Bose leads the three-state sample with $848K of $1.82M |
| Subtitle | Column width = state total; segment height = brand share inside state |
| Axis note | California $724.3K, Washington $533.0K, Nevada $560.9K |
| Footnote | Sample data from FusionCharts Marimekko documentation; percentages calculated from source values, July 2026 |
Frequently asked questions
Does PowerPoint have a built-in marimekko chart?
No. Microsoft Support’s Office chart list, accessed July 2026, includes chart types such as column, line, pie, bar, area, scatter, treemap, waterfall, funnel, combo, and map, but it does not list Marimekko or Mekko as a built-in chart type.
What is the difference between a marimekko chart and a stacked bar chart in PowerPoint?
A stacked bar or 100% stacked column keeps every category the same width, so it mainly shows mix. A marimekko chart changes column width by category total, so it shows both total size and mix in one view.
Can I make a marimekko chart in PowerPoint without an add-in?
Yes, but it is manual. Calculate category widths, calculate each segment’s percent height, draw rectangles with no gaps, stack every category to 100%, and relabel the chart whenever data changes.
What data format do I need for a marimekko chart powerpoint slide?
Use a matrix of non-negative values: categories as columns, segments as rows, and one numeric value per cell. For example, the FusionCharts sample uses states as categories and brands as segments, with nine sales values totaling $1,818,200.
How do I calculate marimekko chart widths?
Divide each category total by the grand total. In the sample, California width equals 724,300 divided by 1,818,200, or 39.84%; Washington is 29.31%; Nevada is 30.85%.
How do I calculate the stacked segment heights?
Divide each segment value by its category total. In California, Bose is 335,000 divided by 724,300, or 46.25%; Dell is 31.08%; Apple is 22.67%.
Is a marimekko chart good for time series in PowerPoint?
Usually no. Domo’s 2026 guidance warns that shifting widths can make trends hard to compare, so a line chart or indexed line chart is usually clearer for time series.
What is the best marimekko chart powerpoint tool?
For licensed business-chart teams, think-cell, empower, Ampler, or Mekko Graphics can be strong choices. For a fast first draft with the chart, calculations, and slide narrative generated together, AnyGen is useful as long as you verify the final numbers.
