Circular flower garden built with retaining wall stones?

I would like to create a circular flower garden in my back yard, and really like the looks of the retaining wall stones that have become so popular. Anyone know of any simple calculations or web sites that will help me to caculate needed materials? and help in the keeping the spacing exact enough to make both levels come out to an exact block count? thus not having to cut the blocks.

Although not exact, measure the length of the block and divide it into the perimeter of the bed. Many of the blocks are longer along the midline of the length for flexibility. Adjust the perimeter to come up with whole blocks.

A bed sixteen feet in diameter would have a perimeter of 50 feet divided by the 16 inch length of a block would indicate approximately 37 blocks to lay the perimeter. Each course of blocks would take the same number.

You calculate the perimeter by multiplying the diameter by pi.

Hope this helps.

Chris,
Thank you for the information, it will work. I have one other question though. The retaining wall blocks have a lip on the back and bottom of the block and will cause the circle to get smaller as each layer goes on. Should I just chisel off the lip, since the blocks really will not be supporting much weight? or just take the measurement for the to circle of blockes?

I would leave the lip in place because it seems that even a three course wall looks nicer with the setback. Of course, it is up to you.
