This will calculate the amount of space you need to create a scale model of the Solar System based on the size you’d like the Sun to be. The bigger the Sun, the more room you will require.

If you decide to make the Sun just 10 millimetres in diameter, then you should be able to use a standard roll of toilet paper to construct the model on, if the Sun is on the first sheet and Pluto on the last sheet.

If you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. A standard roll of toilet paper has about 450 sheets that are about 4.375 inches long, hence the roll is about 164 feet long. You should check your toilet paper for length. Some are longer.

And yeah, no Uranus jokes, ok.
