To maintain minimum social distancing of six feet, a thousand delegates would have to be seated twelve feet apart to allow aisles in between for people to come and go. The seats themselves and some kind of table would take up about two feet on each side, at least.
32 rows of seats * 2 feet each = 64 feet. 31 aisles * 12 feet each = 372 feet. 64 + 372 means we're talking about an idealized square 436 feet in length on each side to seat 1,024 delegates. There are 1,046 delegates, so you'd also need a bit of another row for them plus somewhere to seat potentially hundreds of alternates, but let's just set them aside.
1,024 socially distanced seats would require at least 190,096 square feet. That's for it even be theoretically possible to keep everybody at least six feet apart. That doesn't include any ancillary space needed like a stage or somewhere to collect and count ballots or anywhere for support staff.
In other words, 4.3 acres. If it helps to visualize, a football field is about an acre. So, imagine a thousand people in an indoor space spread out over four football fields and part of a fifth.
You better have a good set of binoculars, and if you're in a larger state you're going to need a delegation chair with a voice that carries. But we will have, in the most absurdly literal sense imaginable, satisfied the demand that everybody must be surrounded by the same four physical walls or else it doesn't count.
