Minimum 60" long and 36" wide

Preference 66" long and 42" wide

To size a chandelier for your dining room, or to be the focal point of your space, measure the length and width of the room and add those figures together. The sum, converted to inches, will equal the diameter that you can use as a guideline when selecting the size of your chandelier. Example: 14' + 20'=34' Converted to inches = 34" Correct Size Chandelier=34" Diameter. If the resulting measurement (room length + width, converted to inches) seems inappropriate due to the size of your table, size your chandelier three quarters the width of your table.

Chandelier is usually half the size of the table. So, around 60" for your new table.

Your chandelier is quite high. When the new table comes, lower it to around 34"...no higher off the table top.

Lamps USA...she want to size a table, not a chandelier.
