Michelangelo's frescos covers the whole of the ceiling of the Sistine Chapel. Therefore, it is the same size as the interior of the chapel: 40.9 metres (134 ft) by 13.4 metres (44 ft) ,
It's about 40 meters (131 feet) long by 13 meters (43 feet) wide. These numbers are rounded off just a little bit. Michelangelo painted over 5,000 square feet of frescoes.

I am pretty sure there are convents ( communities of nuns) within the Vatican,. I am positive there are sisters who work in the Vatican in various capacities ( Linguists, various types of academic roles, secretarial) but may actually reside elsewhere. Rome is a big city and has over 400 churches- most of one denomination , Roman Catholic. I seem to recall there should be some residential convents within the Vatican ( and possibly cemeteries related to them) but cannot pin it down. and while on the subject of Vatican City- the Sistine Chapel is NOT a convent! Name derives from Pope Sixtus who had it built. Does not refer to ( sisters) . When I was a kid I thought- as there was a Franciscan Friary in Hoboken, well the Sistine Chapel was either a convent or a special chapel reserved for Nuns! Not so.
