You can use the mat to square the fabric, then measure and cut by ruler OR use the mat to square and measure, then just use the ruler as a cutting guide. I think the trick is to be consistant. A dear cousin, who's my quilting mentor, also advised me to stick with one brand of ruler because they're usually consistent within a brand, but not necessarily so from brand to brand. I'm guessing this is probably also true for cutting mats. Hope this helps you make your decision.
