Standard size for a U.S. flag to be draped over a casket is now 5’ by 9.5’, or 60” by 114”. Are WWII casket flags of the same size? And, is (or was) it that such flags had no grommets, seeing how they were meant to be properly folded and presented to the deceased’s nearest survivor? According to the VA, casket flags — modern ones — aren’t meant to be flown. They’re made of a lightweight cotton cloth and wouldn’t stand up to the weather for long.
