What data do I need for a US House seat chart?

Two columns: a party (or group) and its seats, in the order they sit from left to right. Add a third column of colours (like #E4003B) to use party colours. The House has 435 seats, so 218 is a majority. Paste it from Excel or Google Sheets, upload a CSV, or connect a live Google Sheet.

When should I use a US House seat chart?

Use it for House election results, forecasts and the majority line at 218, from the 2024 result to the 2026 midterms.

What's the most common mistake with a US House seat chart?

Forgetting vacancies. Seats empty after a death or resignation make the total less than 435, so add a 'Vacant' row in grey to keep the chamber full.

Yes. Press Play to animate it, record an MP4 or GIF, or download a PNG, SVG or PowerPoint file. In PowerPoint it's added as a high-resolution image. It's free, with no sign-up.
