What Is A Good Size For A Deck?

When considering your deck size, it is hard to give a specific answer. We generally like to give broad answers as to now commit to a specific number.

We tend to answer in one of three ways.

  • Small Deck
  • Medium Deck
  • Large Deck

But what does that mean?

These words are very subjective. What’s large for someone could be small for another.

So how can we have a standard or general understanding of sizes?

Let’s take a look at the word average, even though it can be subjective; we can actually use it as a mean.

The average size deck in The United States is between:

300 – 400 sq. ft

Having this reference, you can now use words such as small, medium or lagre with guidance until you are ready to commit to a specific square footage.

  • A small deck is anything smaller than 300sq. feet
  • A medium deck is between 300 – 400sq. feet
  • A large deck is anything bigger than 400sq. feet


  • Unproportional deck size with the house
  • A deck that is too large can dwarf your house
  • A deck that is too small will get lost
  • Generally, a deck should be wider than it is deep, with the longer dimensions running along the house
