That depends on the eyepiece apparent field of view (AFoV), its distortion, and the net magnification.
Bear in mind most eyepieces have pincushion distortion so through the eyepiece, objects are wider than actual angular size X magification.
For example an eyepiece with a 50 degree AFoV will not quite accommodate the moon at 100X. At say 140X the moon will not quite fit in a 72 but should fit in a 83-degree eyepiece.
