The dimensions of Maruti Suzuki Dzire are 3,995 mm L x 1,735 mm W x 1,515 mm H whereas the dimensions of Maruti Suzuki Alto K10 are 3,545 mm L x 1,490 mm W x 1,475 mm H.
On comparing both the dimensions you can notice that Dzire is bigger than Alto but not much. Also, parking spaces are not allocated edge to edge based on the car size. Most spaces would have a standard size. So, I guess even though the dimensions are slightly different, your friend can use the same parking space. It shouldn't be a problem.
