Bugga, I'm going to use your measurements when I get my board. No sense reinventing the wheel! But you made me think...so I went back and brought out the box of envelopes I bought at Staples. They are called invitation envelopes but the measurements on the box say: 4 3/8" x 5 3/4"......next step, I measured an actual envelope and it is shorter on each side than those measurements! SO, I'm thinking that what I considered A2 envelopes are not true A2 envelopes. Maybe this is what is happening with others?
