What is a Mekko chart?

A Mekko chart (also called a Marimekko chart) is a two-dimensional chart where both the width and height of each bar carry meaning. Column width represents one variable — typically market size or revenue — while the stacked heights within each column show the share breakdown (segments summing to 100%). It encodes three variables: market size, segment share, and segment identity.

What is a Marimekko chart?

Marimekko is another name for the same chart type, named after the Finnish design company. The terms Mekko chart and Marimekko chart are used interchangeably. Both refer to a stacked bar chart where column widths are proportional to a size variable rather than uniform.

When should I use a Mekko chart?

Use a Mekko chart when you need to show market size and share simultaneously — for example, segment revenue by geography, product revenue by customer size, or category spend by department. It answers the question: 'Which segments are large, and who has what share within each?' It's common in strategy consulting and market analysis presentations.

Can I import data from Excel or Google Sheets?

Yes. Copy your data and paste it directly into the editor. Format: one row per segment per column, with columns for the column category (e.g. market), the segment (e.g. competitor), the column size (e.g. total market revenue), and the segment value or share. AECharts calculates widths and heights automatically.

How many columns and segments should a Mekko chart have?

Three to eight columns with two to five segments per column is the readable range. Too many columns compress the narrow markets until they're illegible. Too many segments per column creates sliver-thin slices. Group minor segments into 'Other' if needed.

What is the difference between a Mekko chart and a stacked bar chart?

In a standard stacked bar chart, all columns have the same width — only the stacked heights vary. In a Mekko chart, column width is also variable, proportional to a size value. This means a wide, tall stack in a Mekko chart represents both a large market and a dominant share — a combination that a regular stacked bar can't show in a single chart.

Do I need design skills?

No. Templates are professionally designed — paste your data and the chart builds automatically. Most users create their first Mekko chart in under two minutes.

Is there a free plan?

Yes. All features are free with unlimited image exports. Video exports at 1080p require a Pro plan starting at $19/month billed annually. No credit card required to start.

Can I use a Mekko chart in a presentation?

Yes. The MP4 export drops directly into PowerPoint and Google Slides. Mekko charts are a staple in strategy consulting decks and board presentations where you need to show market landscape in a single, dense slide.

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 (e.g. geography). 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 doesn't 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.
