4′9″ = 57 in. Enter only the boxes you have. Ohio uses required only while under 8 AND under 4′9″; reaching either exits.
Ohio does not legislate rear-facing vs forward-facing by age; it requires a restraint appropriate per the manufacturer's instructions. Best practice from AAP (the pediatricians' association) and NHTSA (the federal highway-safety agency), not Ohio law: rear-facing to age 2+, then a harness, then a booster.

Plain-language summary, not legal advice.
This shows the minimum legal requirement in Ohio, not best safety practice, which is usually stricter, and not legal or safety advice. Always follow your car seat's manufacturer instructions. For the full four-stage rules, front-seat rule, and citation, see the Ohio car seat law reference, cited to Ohio Rev. Code §4511.81 (last reviewed 2026-07-09).
How Ohio car seat law works
Ohio does not legislate rear-facing by age: the statute requires a child restraint for a child under 4 or under 40 lb, but leaves orientation to the manufacturer, so "rear-facing until 2" is best practice here, not law. Its booster rule is one of the more lenient: required only while a child is under 8 AND under 4′9″, so reaching either one exits. Two enforcement points: the booster provision is secondary enforcement (police can cite it only after stopping you for something else), while the car-seat (under 4/40 lb) and belt provisions are primary. Front-seat placement is a recommendation, not law. The fine runs up to $75.
