How Tall Is A Two Story House- Find the Safe and Right Height

2 Story House Height

So, how tall is a 2 story house?

Based on ceiling height, the average height of a 2 story house varies widely. The standard 1 story house height is 10 ft. Here, the actual breakdown is 8 ft. ceiling heights plus 2 ft. allowance for the infrastructure of the roof.

Based on this calculation, the height of 2 story house would be about 20 ft. Unfortunately, there is no “one height” for 2-story homes. There are some factors to consider when calculating the height of two story house.

The height of each story = Ceiling height of the rooms + thickness of the floors between each pane.

In general, we consider, the standard height of a two-story home is 25 ft. from the ground to roof crest. Most of the 2- story houses have height between 20 to 25 feet.

So, what length ladder is perfect for ensuring that you can reach this height safely?

Suppose, regardless of the height (h) there is a safe angle (a) for a ladder.

** The height of the top end of a ladder leaned at a 75-degree angle will be 0.97 the length.**

Not Clear?

A 16 ft. long ladder (when extended) sets up at ¼ rule / 75-degree pitch. If so, the ladder will touch the wall at about 12 ft. 7 inches (13 ft. * 0.97).

Step By Step Calculation

Step 1: Measure the height you intend to reach. Suppose it’s 25 ft.

Step 2: Add 3- ft. to the reach height.

Step 3: Add 1- ft. for every 4 ft. of height.

The summary of the formula:  Height of your house / 4 = Angle (a)

So, a= 25 / 4 = 6

The length of ladder you need = Height of your house + 3 + a

In this example: 25 + 3 + 6 = 34

Hence, to reach the eave of the roof which is 25 ft high, 34 ft. ladder (fully extended length) will be fine for this job.

For painting or cleaning gutters/windows of a 2 story house that don’t need to reach on the roof, a 24- ft. extension ladder is perfect for getting the job done.

More To Learn About Ladder Height and Reach

No matter one-, two-, three- or multi-story home, there are some more essential things to learn about ladder height and reach.

While selecting the ladder height, consider the following things:

  • The highest & safest standing point on the ladder
  • The required sections that overlap
  • The angle of the ladder
  • The extended height above the roofline
  • Step ladder sizing

In fact, the safe length of a step ladder depends on its use and height to the top support point.

Ladder Height vs. Reach Height

(a) Step Ladder Sizing

The maximum safe reach height of a ladder for a person is about 4 ft. higher than the ladder height.
For example, you can safely reach a 12 ft. ceiling on an 8 ft. ladder.

The following table should help you to understand step ladder sizing

Step Ladder Reach Height (Sizing Table)
Ladder HeightReach Height

(b) Extension Ladder Sizing

Extension ladders feature even foot increments, for example, 16 ft., 20 ft., 24ft. etc.  A 20 ft. extension ladder has two 10-ft. sections overlapped with each other. As the extension ladder requires overlapping, in extended position its maximum length is less than the length you thought you bought!

Highest Point the Ladder will touch- The extension ladder should be 7 to 10 ft. longer than the contact point or highest support (roofline or wall).

Highest standing level- The highest as well as safest standing level of a person for an extension ladder is the first four rungs down from the top.  If a person stands higher than this level may lose his/ her balance and will fall.

The following table should help you to understand extension ladder sizing.

Top support points for an extension ladder reflect ladder angle, section overlap or 3-ft. extension above.

How To Put A Ladder Against A House

“1 in 4”- it’s a magic formula for setting up a ladder. So, what does it mean?

Well, for every 4 ft. of height you’re going up, you have to set the ladder base 1- ft. away from the wall resting on.

The maximum ladder working height is less than its overall length. The reasons are:

1.    When you set the ladder up at an angle, it’ll reduce its height.

2.    You must avoid standing on the first three rungs of the top end of a single-, straight- or extension ladder.

Not only ladder sizes, but there are also more factors that you should consider if you want to choose the perfect ladder for 2 story house.

  • Step tool- It’s perfect for those tasks that are just out of reach.
  • Step ladder– This type of ladder is the light and simple solution for tasks that are closer to the ground. It’s fixed-length, single-section ladder.
  • Extension ladder- This type of ladder is ideal for tasks higher off the ground. Extension ladders are typically lightweight and easy to set up. It features a series of single-section ladders that are deployed in a cascading manner.
  • Multi-position ladder- This is the most versatile type of ladder. You can use a multi-purpose ladder as stairway step ladder, leaning wall ladder, twin step ladder, extension ladder, or as two scaffold bases.
  • Work platform ladder– This offers a stable surface and safe standing level to work with a platform to finish your task with ease and safely.

It’s also important to know the load capacity or duty rating of the ladder.

Type 3:  200 lbs (Light-duty- Household use)

Type 2:  225 lbs (Medium duty- Handyman & painter, simple projects)

Type 1:  250 lbs (Heavy Duty:  Industrial, Designed to handle most jobs and projects)

Type 1A: 300 lbs (Extra Heavy Duty- Industrial grade, designed to handle professional needs)

Type 1AA: 375 lbs (Super heavy Duty- Offers maximum durability for tough home or professional use. The weight of the materials carried plus the user weight should be less than the ladder’s weight capacity.)
