How many stones are inside a painting?Updated 2 months ago
Standard Drill Sizes
Diamond paintings use two types of drills:
Square drills: 2.5 mm x 2.5 mm
Round drills: 2.8 mm x 2.8 mm
Since diamond paintings are measured in centimeters, we need to convert the canvas size into millimeters and then divide by the drill size to determine the total number of drills.
