What size travel blanket is best for an airplane?

Most popular airplane blankets fall in the 60x40 to 68x48 inch range, which is enough to cover an adult from shoulders to feet in a seated position without spilling into a neighbor's space. Larger throws (50x70 muslin-style) give more coverage but pack bulkier, while compact 2-in-1 sets prioritize a small folded footprint over full body coverage.
