Q. What bed size should a two-year-old have?

Answer

The length of a kid’s bed can range anywhere from 144 to 166 centimetres and its breadth can be anywhere from 73 to 79 centimetres. If the child is transferring from a cot bed to a toddler bed you might not have to purchase a new mattress right away because kids’ beds need a mattress dimension of 70 centimetres by 140 centimetres. It's the same footprint length as a cot bed.
