Square: (house siding)

Abbreviation: SQ

A Square is a term that is used by Siding Contractors, Installers, Suppliers and Manufacturers that is short for 100 square feet of siding.

Not sure what a "Square Foot" is?
See our: definition of Square Feet.

"Square" Bullet Points:

  • The terms "Square" and "Squares" are very common with Vinyl Siding professionals.

  • Vinyl Siding is typically sold in 2 Square (SQ) boxes.
    • 2 SQ = 2 Square = 200 square feet.

  • Vinyl Shake Siding is often sold in 1/3 Square or 1/2 Square boxes.
    • 1/3 SQ = 1/3 Square = 33.3 Square Feet
    • 1/2 SQ = 1/2 Square = 50.0 Square Feet

"Square" Examples in Communication:

  • Vinyl Siding Installer says, "I installed 5 squares of siding yesterday."
    • That is the same as saying, "I installed 500 square feet of siding yesterday."

  • Siding Manufacturer says, "1 box of vinyl siding contains 2 squares"
    • That is the same as saying, "1 box of vinyl siding contains 200 square feet."

  • Siding Supplier says, "All vinyl siding is $25 Off per Square."
    • That is the same as saying, "All vinyl siding is $25 Off per 100 square feet."

  • Vinyl Siding Contractor says, "We pay $100 per Square for Vinyl."
    • In this context, he's refering to what they pay thier installers to install vinyl siding.
    • This would be the same as saying, "We pay $100 per 100 square feet for Vinyl" and "We pay $1 per square foot for Vinyl."

So What is the definition of a "Square" of House Siding? 

A "square" is a unit of area measurement used in House Siding (specifically Vinyl Siding) that equals one hundred (100) square feet.
1 Square (of House Siding) = 10 feet X 10 feet = 100 Square Feet.

10' x 10' = 100 sq.ft. = 1 Square of Siding

Using the formula above, let's bring this all together.

Example:  If you have a wall on your house that is 40 feet long by 8 feet high. ( 40' x 8' )

So How Many SQUARES is this example wall?

Answer: 40' x 8' = 320 sq.ft. = 3.2 Squares of Siding
a.k.a.: 320 ft2 = 320 SqFt = 320 sq.ft. = 320 Ext. SqFt

Now if a product costs $150 per square and you need 3.2 squares, your cost would be $480.00.

$150 per square  x  3.2 squares  =  $480.00
