Altering the dimensions of something is a process that involves changing the size or shape of an object. The two crossword solutions for this term are 'resize' and 'rescale'. Resizing is the process of changing the size of an object, while rescaling is the process of changing the proportions of an object. Both processes involve altering the dimensions of an object, but they are slightly different in terms of the end result. Resizing an object will change its overall size, while rescaling an object will change its proportions without necessarily changing its overall size.
