I finally measured my blade's kerf and it explained so much

I was cutting some dados last week for a bookshelf I'm building in my garage (a small one, nothing fancy). Kept wondering why my joinery was a hair off even though I measured everything twice. Then I dug out my calipers and measured the actual kerf on my combo blade - it was 0.125" instead of the 0.098" I assumed it was. That little difference added up across multiple cuts and threw off my spacing by almost a quarter inch. Has anyone else had a project go sideways because they never checked their blade's real kerf?

Quarter inch over multiple cuts is annoying but honestly man that's still within the range where you can fudge it with some sanding or a shim. Ive never even measured my kerf and my shelves hold up fine, theyre not museum pieces. Seems like a lot of fuss over something you can fix with a quick pass of the block plane.

Check your blade's specs online too, that caught me once.

Check your blade's specs online" - did your actual measurement match what they claimed it would be?
