# How Much Siding For A 10’x12′ Shed? (Drawings Included)

For a 10×12 ft. shed, approximately **280 sq. ft. of siding is needed**, here is a practical example with drawings and measurements to give you as close an idea as possible.

We have as an example this 10×12 feet shed model, in its front it has a double door, a window opening, and another window opening on its left side.

The front facade has footage of 33.61 ft².

The front facade has footage of 81.22 ft² without taking into account door and window openings. The back of the shed has no window or door openings so it is also 81.22 ft².

The right side has footage of 85.53 ft².

The left side has footage of 76.67 ft².

And without taking into account the window opening it would be 85.53 ft².

**In summary, for this shed example, we have:**

Side | Square Feet |
---|---|

Front Side | 33.61 sq. ft. |

Right Side | 85.53 sq. ft. |

Left Side | 76.67 sq. ft. |

Back Side | 81.22 sq. ft. |

Total | 277.03 sq. ft. |

## How much siding do I need to cover 277.03 square feet?

Siding is usually sold by square, where one square equals 100 square feet. So, if you look at this situation, you will need a little less than three squares of siding, because 277.03 is a little more than 2.77 squares.

Of course, it’s a good idea to buy a little extra to account for any mistakes or unexpected issues that might come up during the installation process. **So, rounding up to the nearest whole square, you should consider purchasing three squares of siding for this project.**

## What if your 10’x12′ shed has different doors and windows than the one in this example?

For this case, I will give you the total square footage of the 10×12 foot shed with no openings, and with this information, you just subtract the square footage of the door and window gaps from your own project.

**Of course, you must take into account the height of this example shed.**

Side | Square Feet |
---|---|

Front Side | 81.22 sq. ft. |

Right Side | 85.53 sq. ft. |

Left Side | 85.53 sq. ft. |

Back Side | 81.22 sq. ft. |

Total | 333.5 sq. ft. |

The total area of all sides combined is 333.5 square feet, that is, without excluding any door or window openings.

## Does your shed have windows and doors? If so, what are their sizes?

When you’re figuring out how much siding you need for your shed, the doors and windows make a big difference. If your shed has a door and a couple of windows, for instance, that’s a pretty good chunk of space you don’t need to cover with siding.

So, you’ll need to measure the width and height of each door and window. Once you’ve got those measurements, you multiply the width by the height of each one to get the square footage. So, if you have a door that’s 3 feet wide and 6 feet tall, that’s 18 square feet right there that you don’t need siding for.

And the same goes for windows. If you have a window that’s 2 feet by 2 feet, that’s another 4 square feet to subtract from your total siding needs.

After you’ve figured out the total square footage of your doors and windows, you subtract that number from the total square footage of your shed walls. This gives you a more accurate idea of how much siding you’ll actually need to purchase.

## What is the coverage per piece or per square for your chosen siding material?

Alright, the coverage per piece or per square of siding can vary quite a bit depending on the type of material you’ve chosen.

If you’re looking at vinyl siding, for instance, a common size is a double 4″ panel, which is about 8″ wide and 12′ long, and each panel covers about 8 square feet.

This means that if you’re buying in squares, each square, which is a 100-square-foot unit, would contain around 12.5 panels.

If you’re thinking about wood siding, say cedar shingles, it’s a different story. These are often sold in bundles, with each bundle covering around 25 square feet when you’re working with a standard 5″ exposure (which is part of the shingle that’s visible after installation).

So, you’d need four bundles to make up a square.

But again, these are general estimates. The actual coverage can vary based on the specific product, the manufacturer, and even factors like how much overlap you’re planning in your installation.
