You may consider a larger space if you have a congregation with many elderly people. Pew lengths vary from 5 feet to 24 feet. The usual length of a row is 24 feet, but that could be adjusted, depending on fire and building codes in your area. Movable pews provide the formal look of traditional seating, but they can be realigned. Pews are heavy, however, and cannot be stacked.
Movable pews can slide, too, which makes it difficult to maintain consistent spacing between rows.
Manufacturers generally recommend that pews not be moved. Some will void their standard 20-year warranty if you don't bolt your pews in place. According to Sherry Rains, a representative of Rainsville Church Pew Manufacturing, bolting the pews to the floor is done without extra charge. The lead-time from order to installation of pews is about three months. Unexpected Choices Churches that are getting up there in years aren't the only ones opting for pews.
