It is just the way math works. Examples to follow. We price our signs and plaques using some math and some magic. Two signs of equal size are not normally the same price. Our pricing is dependent upon not only size, but on the font used (we often spend a lot of money for the rights to use a particular font), complexity of design, amount of hand finishing required, and other secret stuff that we won’t divulge.
Back to the math. Whether a rectangle or a circle, increasing the size by, let’s say, 10%, actually increases the area, and therefore the amount of materials we use by 21%. A plaque that is originally 10 inches square would be 100 square inches. Increasing that size by 10% makes a sign that is 11 x 11 inches. Do the math and the new size is 121 square inches. Or 21% greater in area. Therefore, you should expect the new price to be about 21% greater for a plaque that has only been super-sized by a lousy 10%. Don’t hold us to the 21% rule, as there are other mysterious factors involved here.
