I was reaching for the flute pad case and my hand hit it wrong and I spilled all the pads. About two thousand pads on the work bench and floor. I said "I wished I did not do that ).Well that is really not what I said.

So here is my plan. Glue small strips of wood on a piece of cardboard use a pad of known size to set the distance . Do this for all the pads. Like railroad tracks. If a pad fits just right between the tracks I then know the size.

I have been telling the young man I have been training for the last two years that one day he will spill the pads , then I go and do it.

There's the Pad Size Tool http://www.padsizetool.com/
I have one and it works fine.
If you get one then first measure a few pads yourself and compare them with the tool, it might be a bit too big or small in comparison with how you or your supplier measure the pads.

The tool Nitai refers to works fine, its also easy enough for yourself to print out a scale on a computer as well and stick down on a piece of wood

One advantage in keeping separate sizes in separate containers, ideally closed.

My daily use supplies are in individual drawers, and I dread an earthquake! (Fortunately I'm 100 km from those major quakes that have wrecked Christchurch here in NZ.)

My bulk is safely in plastic bags.

The device can be adjusted to give readings that you desire.
