8 x 70 x 42 Flat-Panel TV Boxes safely ship flat panel TVs. Corrugated Moving Boxes FOL - Full-overlap flaps on top and bottom for support. Flat-Panel TV Boxes contain heavy-duty corrugated for added protection.

 

A box with the dimensions 70" x 8" x 42" is best suited for 70-inch to 75-inch flat-screen TVs.

 

Here is the breakdown of how the different sizes fit inside that specific box:

 

The Ideal Fit: 75-Inch TV
This is the most efficient use of the space while leaving just enough room for protection.

• TV Dimensions: ~66" wide x 38" tall.
• The Fit: This leaves you with roughly 4 inches of extra width (2 inches of padding on each side) and 4 inches of extra height.
• Why it works: This is the "Goldilocks" size for this box. It is tight enough to prevent the TV from shifting, but spacious enough to accommodate the necessary foam corner protectors.

The Safe/Roomy Fit: 70-Inch TV

• TV Dimensions: ~61-62" wide x 35" tall.
• The Fit: This leaves significantly more room—about 8 to 9 inches of width and 7 inches of height.
• Why it works: You will have plenty of space for heavy-duty bubble wrap or thick styrofoam blocks. However, you will need to use extra dunnage (filler) to ensure the TV doesn't slide around inside the large void.

 

Will an 80-Inch TV fit?
No. An 80-inch TV is typically about 70 to 71 inches wide. It would be the exact width of the box (or wider), meaning there would be zero room for padding, and the box likely wouldn't close.
