Flat cabinet scrapers are measured by their length, width and thickness.
These are the available sizes for flat cabinet scrapers:
Length
Width
100 mm (4″)
50mm (2″)
125mm (5″)
62mm (2.5″)
150mm (6″)
62mm (2.5″)
150mm (6″)
75mm (3″)
The thickness of flat cabinet scrapers ranges from 0.4 to 3mm (0.02 to 0.12″).
When the length of the scraper increases so does the thickness. This provides the larger-sized scrapers with enough strength to scrape without becoming easily damaged.
Having both short and long length cabinet scrapers available means that you can use the longer ones to cover a larger surface and the shorter ones for smaller surfaces.
