Probably an 84 square inch tablecloth. It depends on the shape and size of your table.
Table linen size will depend on the drop you need. For a 5 foot diameter (60 inch) ROUND table and using a 90 inch ROUND tablecloth your drop would be 15 inches all around the table. For a 5 foot diameter (60 inch) SQUARE table and using a 85 inch SQUARE tablecloth your drop would be 12 and a half inches all around.
72 inches
To determine the size of the tablecloth needed for a 42-inch round table with a 4-inch overhang, you would add twice the overhang to the table's diameter. This means you need to add 8 inches (4 inches on each side) to the 42-inch diameter. Therefore, you would need a tablecloth that is at least 50 inches in diameter to achieve the desired overhang.
A 4 x 8 tablecloth would be suitable.
To find the correct size table linens you have to start with shape: square, oval, oblong, or round. Then you must measure the table and account for drop on the sides. Using this formula should give you an estimated size: Length of table + (desired dropx2)=tablecloth length. Width of table + (desired drop x2 ) = tablecloth width.
If the table height is 29 inches then 132 inches tablecloth perfect fit and it will give drop up to the ground.
If the table is 42 inches in diameter and the height is 29 inches then 102 inch tablecloth is perfect fit which gives drop to the ground.
For a square table designed for four people, a tablecloth that is approximately 54 inches by 54 inches is generally a good fit. This size allows for about a 12 to 15-inch drop on each side, which provides a nice drape without being too long. If you prefer a more formal look with a longer drop, you might consider a larger size, such as 72 inches by 72 inches. Always check the dimensions of your specific table to ensure the best fit.
That completely depends on the height of table top above the floor. The width of the tablecloth needs to be the width of the table (60") plus twice the height from the floor. So, if the height from the floor is 30", the tablecloth needs to be 120" wide.
For an eight-foot table, which typically measures 96 inches long, you generally want a tablecloth that is at least 108 inches long to allow for a drop on each side. If you prefer a longer drop, consider a tablecloth that is 120 inches long. The width of the tablecloth should be at least the width of the table, which is usually 30 to 48 inches, depending on the table style. Always check the specific dimensions of your table to ensure the best fit.
If the table height is 29 inches standard then 120 inches is perfect fit, which gives the drop up to the floor.
