Just about every serious tool supplier and a lot of the drill bit manufacturers supply wall charts with drill sizes and tap drill sizes--a lot of them have pocket charts too. We have a bunch of them hidden around the shop.

Online references like that one are real handy when you're sittin' at the computer doing a drawing and planning out a job but when I'm in the shop and my hands are dirty and greasy a laminated pocket chart is the handiest way to figure a drill size...

I have paper chart mounted on one of my shop doors for easy access. and a metal one above my lathe. I just gave a second metal chart to the local heavy equipment repair guy. The metal ones are the best because you can wash them when they get dirty.

It is about 20 X30 and the writing is large enough that my old eyes can read it.
It is also about 50 years old and it has been a long time since I have seen anything at the suppliers. I remember when every supplier had a gimmick give away item sitting on the counter.

Yeah the metal drill chart i believe it what i have and its only 3x8 maybe....
and old as the hills too but just in to bad a shape to read most of it and looks as if it had been rubbed and wiped down so much the thing is thinning on the edges and engraving/stamping... so its prolly not much count...

next time i go in to the quality fasteners place i'm going to ask if they have something large enough to read that is as close to the one Digr posted a link to
and see what they say and which arm or leg is required to give up for such a thing....

For the last ten years or so I've just used the chart in South Bend's old "How to Run a Lathe".

I have a couple fastened inside the lids on tool boxes, and likely a bunch more around somewhere. I don’t have enough wall space for a large one these days.

We used to print them out as well and just put them where they were handy. Get a printout and laminate it and it’ll last a long time.
