About the space between the joists

This is probably a silly question, but I have no clue: For batts/rolls, should I get the 15" wide or the 16" wide ones, assuming that I need two batts side to side to fill up one cavitiy? The exact space in between joists is 30.5". Two of the 15" sound too short, but two of the 16" would be 1.5" too wide, and am concerced about compressing the insulation and loosing R value
:confused:
This question got lost in the thread... but it has become more relevant now because I have the opportunity of buying 15" wide rolls at a large discount. Can I use two 15" wide batts side by side, or would it be too short (given the 30.5" space between joists). Would two 16" batts be too wide? What has been your experience?
