Retool Grid Layout: How to Get More Columns Beyond the 12-Column Limit

If you've spent any time building complex UIs in Retool, you've almost certainly hit the wall: the default 12-column grid layout just doesn't give you enough granularity. Components end up with awkward whitespace between them, or everything feels crowded because you can't position elements precisely enough. This is one of the most-requested layout improvements in the Retool community — and while a native fix is on the roadmap, there's a solid workaround you can use right now to get more columns and finer control over your Retool grid layout.

Why the 12-Column Grid Feels So Limiting in Retool

The 12-column grid is a well-established paradigm in web development — it maps cleanly to CSS frameworks like Bootstrap and makes it easy to divide a layout into halves, thirds, and quarters. Retool adopted it naturally since it runs in that same HTML/CSS world. But there's a big difference between building a marketing page and building a complex internal tool with dozens of components.

When you're laying out tables, charts, filters, forms, and buttons side by side in a desktop-style application, 12 columns simply isn't enough resolution. A few common pain points reported by Retool builders:

• Components snap to positions that are too far apart, leaving dead whitespace
• There's no way to nudge elements by small increments without resizing adjacent components
• Dense data-heavy layouts feel cramped or misaligned
• Even doubling to 24 columns would dramatically improve precision

Retool's team has acknowledged the problem and confirmed that a more configurable grid — with user-definable column counts, widths, and spacing — is planned. But until that ships, you need a workaround that works today.

The Workaround: Use Containers as a Granular Sub-Grid

The key insight here is that every container in Retool has its own independent 12-column grid. That means if you nest components inside containers, you effectively multiply your available column resolution. A container placed in 6 of the 12 parent columns gives its children a fresh 12 columns to work with — inside that half-width space.

The original problem with this approach was that Retool's default Container component adds visible padding, borders, and margins that eat into your layout and make nested containers visually obvious. The fix? Make the container invisible.

How to Create an Unstyled Container in Retool

Retool has made it possible to style containers so they're functionally invisible — no border, no background, no visible padding — while still giving you that nested sub-grid. Here's how to set it up:

• Step 1: Drag a Container component onto your canvas and size it to span the columns you want to subdivide.
• Step 2: In the container's style settings, set the background color to fully transparent (or match your app background).
• Step 3: Remove or zero out the border — set border width to 0 or select "none."
• Step 4: Adjust padding to 0 on all sides so the container's internal grid starts flush with its edges.
• Step 5: Place your components inside the container. They now snap to a 12-column grid within the container's width, giving you much finer positional control relative to the parent canvas.
• Step 6: Repeat by nesting additional unstyled containers if you need even more granularity in specific regions.

This approach lets you create layouts that behave like 24, 36, or even 48 effective columns — depending on how you divide and nest. It takes a few extra minutes to set up, but once you get the hang of the mental model, it becomes second nature.

Planning Your Layout Before You Build

The biggest mistake builders make when using nested containers is jumping straight into Retool without a layout plan. Before you start dragging components, sketch out your UI in terms of regions. Ask yourself:

• Which sections of the screen need the most precise alignment?
• Can I group related components (e.g., a filter bar, a stat row) into a single container?
• Where will the container boundaries fall on the parent 12-column grid?

A useful mental shortcut: think of your top-level canvas as a macro grid for major sections, and each container as a micro grid for component-level alignment within those sections. This separation of concerns makes complex layouts much easier to maintain.

What's Coming: Native Grid Improvements in Retool

Retool has confirmed that giving editors more control over the grid — including custom column counts, column widths, and spacing — is on the product roadmap. This would bring Retool's layout system closer to what you'd expect from tools like Figma or modern CSS grid, where you define the grid rules and components snap to them.

Until that ships, the unstyled container method is the most reliable way to get more granular column control in Retool without waiting. It's not as elegant as a native 24-column grid, but it's production-ready and used by teams building serious internal tools today.

Summary

Retool's 12-column grid layout is a real constraint for complex desktop-style internal tools. The best available workaround is to use invisible, unstyled containers as sub-grids — each container resets the column count to 12 within its own width, effectively multiplying your layout precision. Set container backgrounds to transparent, borders to none, and padding to zero, then build inside them as you would on the main canvas. It's a workaround, not a fix — but it works, and it works well.
