Question:
LCHACHILA where should a mezuzah be placed? Assuming 80 inch door post. Upper 1/3 begins at 53 1/3 inches from the bottom (80/3 =26.67. 80-26.67=53.3). Should the MEZUZAH be placed at right above 53 inches exactly? It seems too low. Or l’chatchilla can it be placed between a TEFACH from the top (4inches CHAZON ISH) and 53 inches from the bottom. Anywhere in between as long as its the upper 1/3 and a 4inches from the TOP? LECHATCHILLA
Answer:
The best place to put the mezuza is right after the beginning of the top third of the doorway. Although it is still kosher if it is higher, until a tefach before the top of the doorpost, the best place to place it, is as stated.
Best wishes
