Highlights
The short answer
Any traveller booking a KTX ticket for a child can expect a discount rather than a full adult fare: children aged 6 to 13 get 50% off, and toddlers under 6 get 75% off, up to two children per accompanying guardian. A toddler who does not need their own seat is not charged for an additional ticket at all, checked against the current official Korail FAQ.

Do children need a ticket on the KTX?
Yes, but at a discount rather than the full adult fare. Children aged 6 to 13 get a 50% ticket discount; toddlers under 6 get a 75% discount, up to 2 children per guardian, and ride free if no seat is required
How much is the child or toddler fare?
Child (6-13) fare is a 50% discount off the adult fare; toddler (under 6) fare is a 75% discount, and free if the toddler does not need a seat
What if my toddler doesn't need their own seat?
If the toddler travels on your lap and does not require a seat, no additional ticket charge applies, based on the same guardian.
What if I have more than two young children?
The discount is stated as applying up to two children per accompanying guardian, so travelling with a third young child may need a second adult in your party to claim the discount on all of them.
How do I book a ticket at the station itself?
Tickets can be bought via the KORAIL website, the KORAIL Talk mobile app, ticket vending machines, or at train stations (not available at subway stations)
Questions people ask
Is the child discount automatic when I book online?
