Mekko Chart Maker

Show size and composition at once

A Mekko, or Marimekko, chart is a two-dimensional stacked bar chart where column width shows each category's total and segment height shows its internal composition, so cell area is proportional to the actual value. InstaCharts builds this market-share favorite straight from your spreadsheet.

Use cases

When to use a mekko chart

Best uses

  • Show that one category is larger than another and how each is composed
  • Compare segment share across markets of different sizes in one view
  • Visualize how a budget or resource is split within departments
  • Present a two-level categorical breakdown with one numeric measure

When another chart fits better

  • Many thin segments become unreadable; group small ones into Other
  • For exact numbers, use a table or stacked bar chart
  • Mekko charts are not designed for negative values

FAQ

Mekko Chart maker FAQ

Answers to common questions about making a mekko chart with InstaCharts.

Is the Mekko chart maker free?

Yes. Creating and exporting a Mekko chart is free with no account. The free tier supports up to 500 rows and adds a watermark; paid plans from $10 user/mo remove it.

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

A stacked bar chart uses equal-width bars, so only height carries meaning. A Mekko chart also varies the column width by the category total, so both width and height encode data and cell area reflects the absolute value.

What data do I need for a Mekko chart?

A category column for the columns, a numeric value column, and a breakdown column for the segments within each column. InstaCharts can pivot raw data into this shape automatically.

When should I use a Mekko chart?

Reach for a Mekko chart for market-share and resource-allocation analysis, where you need to compare both the size of each category and how it breaks down internally in a single picture.
