Measuring diameters

[itunu]

I'm fairly new at candlemaking and have a couple of questions about diameters. To work out the correct diameter of a container (so I can get the right wick) do I measure to include the glass walls or do I just measure the inside part - ie where the wax is actually going to be.

To complicate things further, if my container is hexagonal do I measure the widest part?

I'm trying to work out the diameter of this glass hexagonal jar in cm - See photos - http://www.flickr.com/photos/30114490@N07/

(Please ignore the photo of the tin and soap)

Measure the inside of the glass and for the hexagon jar it looks like 5 cm to me, take a bit off for the thickness of the glass wall.

I would treat a hex jar as a cylinder and measure the inside diameter. Make a paper cylinder that fits snug and measure that. Variables that you can't really get a good handle on are the square sides of the hex and the effect of glass thickness. The diameter will get you in the ballpark and you can tweak from there.

Here's a handy calculator.

The volume, of course, would be the area X the height of the jar. HTH

Thanks for your advice. I will test some wicks and hope one works.
