Mass. A refracting telescope needs to be either really long, or have really thick lenses. In either case, the mass of the telescope limits how large you can make it, if you want to be able to change its direction.
The side is determined by how far apart the ends are.
Images are not always clear because the light is being bent.The size of the lens is limited which limits the power of the telescope.
the hubble telescope is a refracting telescope and it is the biggest one because the refracting telescope can only have a certain range of size for the glass lens because it can only hang on the telescope and it is aproximently 5 meters big the lens. hope it helped
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths

Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
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]

According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
