Arch Measurement

St. George's School of Montreal

Published on 2019-12-04


I'm wondering if anyone would be willing to share their measurements for the arch.
Currently we know the top is 45.75" from the ground, and that the arch's horizontal diameter is 73".
I'm wondering if anyone knows how wide the flat section in the middle is, as the arch is not a perfect semi-circle.
Any info appreciated!

The flat section is about 9 inches. The link below is a sketch of the arch with our compiled measurements. 

Hope this was helpful!
