Baby Gear Tools: Fit, Size, Safety & Checklists

Free tools

The questions before you buy, answered in a click

Eight free tools for the things that are genuinely hard to work out — whether a car seat fits your actual car, which seat suits your child’s height and weight, what size clothes to pack, and when your baby is due. No account, no email, no paywall, and nothing to install.

Why these exist

The numbers are the hard part

Most baby gear pages tell you a seat is “compact” or a bassinet is “roomy”. Neither helps when you are standing in a car park with a tape measure. These tools use published dimensions and safety limits instead of adjectives — the same figures you will find cited on every review here.

Nothing is gated

No account, no email capture, no “unlock the full results”. If a tool cannot answer your question with the data it holds, it says so plainly rather than guessing a number to look useful.

Kept current

Car seat limits change when manufacturers revise a model, and recall notices go up without warning. The recall search reads from the US CPSC feed, and the seat specifications behind the fit calculator are re-checked on a schedule against the manufacturers’ own published figures.

Where the data comes from: manufacturer specification sheets, the NHTSA and CPSC public databases, and the published safety standard each product is certified to. Where a figure could not be verified against a primary source, it is left out of the calculation rather than estimated.
