The lenses used will determine the magnification ability of the telescope. But they also need to fit in the tube or corrugated paper you use to form the base of the telescope.

A lens-based telescope relies on a process called refraction, which is essentially the bending of light when it passes through a different medium. When a lens is fitted inside a telescope ...

Curved lenses, used for centuries, become heavier and bulkier as their capacity increases. This limitation is particularly problematic for space telescopes, where every gram counts.
