Mekko Chart Maker — Create Marimekko Charts Online for Free
A Mekko chart, also called a Marimekko chart, encodes two variables at once: column width shows market or category size, and stacked height shows the share breakdown within each column. Use AECharts to build Mekko charts from your Excel or Google Sheets data for market landscape analysis, competitive positioning, and strategy presentations.
How to Create a Mekko Chart
Select the Mekko chart type
Open the AECharts editor and select Mekko Chart from the chart type picker. If you want a different visual style, browse the template explorer on the right panel and click any template to apply it instantly.
Enter your data
Click "Edit Data" in the top-right corner to open the spreadsheet. Put your category names in the first column — each row becomes one stacked column in the chart. Add values in the columns to the right — each additional column becomes a segment stacked within each category. AECharts calculates column widths and stacked heights automatically. Import directly from Excel or Google Sheets, or upload a CSV or Excel file.
Adjust styling
Use the top menu bar to customize the look. Set a color for each segment so they stay consistent across all columns. Adjust stroke color and stroke width on the bars, plus the usual label, tick, axis, and grid options — font, size, and color. Every change previews instantly.
Export
When you're ready, export as a static image (PNG), an animated video (MP4 at 1080p), or a PowerPoint file. MP4 embeds directly into slides and social posts; PNG works for reports and print; PPTX lets you keep editing in PowerPoint.
Mekko Chart Maker Features
Two Dimensions, One Chart
Column width encodes market or revenue size. Stacked heights encode segment share. A single chart communicates what usually takes two charts plus a table.
Automatic Width Scaling
AECharts calculates column widths proportionally to your size values. No manual pixel sizing. Change a market size value and the chart redraws instantly.
Video & Image Export
Export as MP4 at 1080p or as a static image. Works in PowerPoint, Google Slides, LinkedIn, and reports.
Consistent Segment Colors
Each segment keeps the same color across all columns. Audiences can track a segment through the full market landscape without reading labels at every bar.
Real-time Preview
See every change instantly. What you see in the editor is exactly what exports.
No Design Skills Needed
Templates are professionally designed. Import your data, adjust colors if needed, and export. Most users are done in under two minutes.
When to Use a Mekko Chart
Mekko charts work best when both the size and the composition of categories matter, when a stacked bar chart would miss the fact that some markets are much larger than others.
Market Landscape
Column width = total market size per segment. Stacked height = market share by competitor. One chart shows where the large markets are and who dominates them.
Revenue by Customer Segment
Column width = total revenue per product. Stacked height = share by customer size (enterprise, mid-market, SMB). Reveals where revenue is concentrated and how exposure varies by product.
Portfolio Analysis
Column width = category spend. Stacked height = vendor share. Procurement teams use this to find consolidation opportunities across a complex supplier landscape.
Channel Mix
Column width = total sales per region. Stacked height = channel share (direct, partner, online). Compare how channel strategy differs across markets.
Competitive Positioning
Column width = segment size. Stacked height = share of wallet. Used in strategy consulting to surface where a client is strong, weak, and where white space exists.
Budget Allocation
Column width = total budget per function. Stacked height = sub-category share. Finance teams use this to visualize how resource allocation compares across departments.
Mekko Chart vs Stacked Bar Chart: Which Should You Use?
Both show segment breakdown, but Mekko charts also show size.
Mekko Chart
Best for: Market analysis where both the size of each market and the share within it matter.
Strength: Encodes three variables in one chart: column size, segment share, and segment identity. Standard in consulting and strategy decks.
Use when: Market landscape, competitive positioning, portfolio analysis, channel mix by region.
Stacked Bar Chart
Best for: Showing part-to-whole breakdown across categories when all categories are comparable in scale.
Strength: Cleaner and easier to read. Better when the audience does not need to account for differences in category size.
Use when: Revenue mix, budget allocation, survey results, when columns represent comparable totals.
If the columns in your stacked bar chart all have the same total, use a stacked bar. If the column totals differ significantly and that difference is part of the story, use a Mekko chart.
