I'll pretend this is the right category. I have what I think is a bit of a silly question.

I'm trying to put a coat rack up and decided to use anchors for the screws. I've never really used them before. These are just the very plain plastic anchors -- the kind that look a bit like a fat screw, w/no extra stuff. I don't even know what size they are, but I'm fairly sure I was intending to use the 10 x 1.25" wood screws. And the screws feel like they're screwing into them nicely, and they're the same length. So I'm going on the presumption they are 10 x 1.25" anchors.

The problem is I don't know how big a bit to use to drill the hole. The thing looks to be about 1/4" at the top (without the "head") and I know the bottom will expand when I put the screw in. Do I want a bit the same size as the top end of this thing? I'm trying to do this in plaster and if I screw it up (pardoning the pun), it isn't going to be an easy fix.

I can't tell from your description which type of anchor you have. Often the packaging will tell you the size drill to use , most often not. If you have the first type shown you would drill a hole that the pointy end will go into. These types are for drywall. I don't think they will work on plaster wall however. The second type, you drill a hole the anchor will fit into tightly. This type would be better for plaster. Do not worry about screwing up, plaster and drywall holes like you are speaking of are very easy to repair. Drill a hole in a piece of scrap wood to test hole size.

That's easy for you to say. :) I have no clue how to fix plaster and this was only supposed to be a 15 minute project.

It's like the yellow one.

Testing on the wood is a good idea. Thanks. Sounds easier then fixing screw-ups.
