Will it Fit? — Trunk Space Checker

Check if furniture packaging fits in your car trunk before driving to the store. Auto-detects dimensions from any product page.

Stop making unnecessary trips to the store only to discover your new furniture won't fit in your car. Will it Fit? is a free shopping companion that lives in your browser's side panel. Navigate to any furniture or home goods product page and it automatically reads the packaging dimensions — no copy-pasting URLs, no manual searching required. HOW IT WORKS Open the side panel on any product page. The extension reads the packaging dimensions automatically. Select your vehicle from the database, add your items, and hit Check. You get a full 3D visualization showing exactly how everything loads into your trunk — not just whether it fits, but how to orient each box. WORKS ON ANY SHOPPING SITE The extension automatically detects product dimensions on most major retailer websites using structured data. For sites without structured data, it uses AI-assisted extraction — just add a free Anthropic API key in settings and it works everywhere. CAN'T FIND DIMENSIONS? NO PROBLEM If a page's dimensions can't be detected automatically, you can enter them manually in seconds and still get the full fit check and visualization. VEHICLE DATABASE Covers hundreds of North American sedans, SUVs, trucks, minivans, hatchbacks, and wagons from model year 2000 through 2024. Trunk dimensions are based on published manufacturer specifications.
