Is there a formula to figure out how to lay out metric shingles so as not to have small tabs on the ends. Need help soon. Thanks

One Meter = 39.37 Inches
One Centimeter = 0.39 Inch or 4/10ths of an Inch
(If you're asking about the metric system.)
Or use an engineer's measuring tape (tenths of an inch). One Foot = 4.7 Centimeters.
Measure a shingle width, and your roof width plus 3/4" overhang on both ends, and convert it to inches to calculate the layout.
Stagger the tabs, just as you do with non-metric shingles.
Good Luck!
