Graco Size4Me 65 fit guide
Simply-Safe-Adjust harness convertible — grows without rethreading the straps. Here's exactly which children it fits, how NHTSA rated it, and which cars it fits — including three-across.
Which children it fits
| Mode | Weight | Height | LATCH limit |
|---|---|---|---|
| Rear-facing | 4 lb – 40 lb | up to 49" | up to 50 lb on lower anchors |
| Forward-facing harness | 22 lb – 65 lb | up to 49" | up to 50 lb on lower anchors |
Weight/height limits are the seat's NHTSA-published values. Beyond the LATCH limit, install with the vehicle seat belt instead of the lower anchors. Always follow the labels on your seat and the vehicle manual.
NHTSA Ease-of-Use detail
NHTSA's Ease-of-Use rating measures how easy a seat is to install and use correctly — the single biggest factor in real-world safety, since most seats are installed wrong. It is not a crash-test score; NHTSA does not crash-rate individual car seats.
Which cars the Size4Me 65 fits three across
At 19" wide, three Size4Me 65s across is only realistic in the widest minivans and full-size trucks. For three-across in a normal car, see our narrowest convertible car seats.
