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. AAP/NHTSA best practice (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 worth knowing: 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.
