Car Seat Measurements
What is the narrowest booster seat? Which seat has the highest top harness slots? which one has the tallest seat back? The answers to these questions help you figure out:
- Which seats will fit, side by side, 3 across?
- What is the best harnessed seat for a child with a long torso?
- Which high back booster will last the longest for a tall child?
We took a common measuring tape to many of the most common (and a few very unusual) car seats and boosters. In general, We took the measurements on top of the cover, pushing down hard to simulate a heavy child. We measured to the middle of each harness slot. Width refers to outside width, not seating area. We'd say there is a margin of error of at least 1/2 inch, but you should be able to compare seats with each other pretty well. The starting point for these measurements can be difficult to determine, so We've just done my best to keep things consistent.
To get more information on each seat, check out the Buying Guide. You can also find information on each manufacturer's web site
