The cyclic isomers with 6-membered rings don't have this eclipsing interaction and so should be more stable (lower energy) than the isomers with 5-membered rings. So based on bond energies and steric interactions, we would expect that the 6-membered ring form of the cyclic sugar should be favored. Entropy Changes my watenfall
