Cant remember sizes for hand luggage with ryanair but you are allowed one piece of hand luggage no more than 10kg I believe. As for checked in baggage your allowed 15kg per person but must pay to check a bag in. Its £3.50 per checked in bag which must be payed for at time of booking,if not its £7.00 per checked in bag at the airport. If your over your 15kg then its £5.50 per kilo excess, Hope this helps.
