Hello Somayeh,
The cell size is defined in the header of the input rasters. Any size is fine, but all the input data must have the same cell size. Also, the unit must be meters.
For example, the header for a recent project we ran looked like this:
ncols 11763
nrows 17422
xllcorner 4.08044000000000E+0005
yllcorner 4.10364100000000E+0006
cellsize 6.096
nodata_value -99
Hope this helps.
