There are many types of arches: some of them are half round, others are flattened (segmented), and still others have more than one curve to them (elliptical).
Because of the manufacturing process, each type and each size of arch requires a different mould so the combinations of shape and sizes are endless. Unfortunately, the manufacturers do not have endless space to store their moulds so the chances of an existing arch mould matching the dimensions on your plan or existing arch are very low.
And, while you can get custom sized arches made, they come with a hefty price tag.
