rectangle-packer
Pack a set of rectangles into a bounding box with minimum area
Decision gist · record as of 2026-08-14
Yes. The package is stable (Production/Stable status), actively maintained, has no known vulnerabilities, and solves a well-defined problem with a clean API. The medium install friction is offset by precompiled wheels for common platforms and Python versions. Install it if you need to pack rectangles efficiently.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- Medium install friction due to compiled wheels for multiple platforms and Python versions (3.9–3.14).
- Active maintenance with recent release (155 days ago) and no known vulnerabilities.

Import the module and call pack() with a list of (width, height) tuples to get (x, y) coordinates for each rectangle's lower-left corner.- Whether the packing algorithm guarantees optimal solutions or uses a heuristic approach.
- Performance characteristics (time/space complexity) for large numbers of rectangles.
- Whether rectangles can be rotated or only placed in fixed orientations.
What it is and what it does
rectangle-packer is a Python library that solves the 2D rectangle packing problem: given a collection of rectangles with fixed dimensions, it arranges them into a bounding box with minimal area and no overlaps. The package is implemented in C for performance and exposes a simple Python API that takes a list of (width, height) tuples and returns the (x, y) coordinates where each rectangle should be placed.
The library targets developers working on layout problems in graphics, game engines, texture atlasing, or any domain requiring efficient spatial arrangement of rectangular objects. It has no runtime dependencies and supports modern Python versions (3.9 through 3.14) across Linux, macOS, and Windows with precompiled wheels.
Use it for
- Generate texture atlases for game engines by packing sprite sheets into minimal-area canvases.
- Optimize UI layout in graphics applications by arranging rectangular elements with minimal wasted space.
- Arrange rectangular bins or containers in warehouse or logistics planning simulations.
- Pack rectangular images or tiles into a single image file for efficient storage and rendering.
- Solve bin-packing problems in manufacturing or material-cutting scenarios.
