If you are comparing the biggest telescopes in each type, that's because a large refracting telescope needs a huge lens, which gets expensive; also, the lens can't be supported, while a mirror can.
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
