How To Choose The Best Adjustable Ladder For Stairs

The market is flooded with different brands, types, and models of ladders. So it’s easy to become overwhelmed when choosing a ladder to use on stairs. You should have a clear idea about the stair ladder’s features before investing your penny. Since your safety is also related to the ladder, you can’t ignore it. Let’s note down some fundamental factors to pick the right multi purpose ladder for stairs.

Construction materials

The ladders are made with different materials, including aluminum, steel, metal, fiberglass, and wood. However, these materials will make a ladder sturdy enough but not better for stair. As your target is to use the ladder on the stairs, you should choose an aluminum-made ladder because it is lightweight to carry but can load maximum weight.

However, if you want to use the ladder on the stairs with electricity connections, you should choose a fiberglass ladder instead of aluminum. Fiberglass is non-conductive to electricity. So you’ll be free from electric shock while doing any electrical work by climbing this ladder.

Multiple height adjustments

It’s tough to define a specific height for a stair ladder because you may need to use it on different surfaces for different purposes. In that case, a multifunctional and easy height adjustable ladder can be the right match for you. It’ll keep you tension free about the ceiling height. Most multi-positional ladders come with 5 configuration height adjustments from 6′ to 22′. So that you can use it everywhere.

Easy to use

All the stair ladders are attached with easy push knob hinges and rock locks. As you have to change the ladder’s height frequently, that’s why they bring these easy locking and unlocking mechanisms.

By pushing the hinge locks and squeezing the rock locks, you can transform the ladder position from A-frame to extension mode, staircase mode, scaffold mode, etc. You must carefully secure your position before finally setting up and climbing the ladder.

Supportive weight

You should consider how much weight the ladder can support unless you want to fall flat from the ladder and visit a hospital by breaking your legs or hands. If the ladders are built with solid materials, they can support 200-350 pounds. Though the more weight they support, the more expensive they will be!

But your life is more precious than money. However, that doesn’t mean you choose an expensive ladder unless you need 350 pounds of support. In that case, you can choose a ladder that can support 250-300 pounds if that meets your expectations.

Stability and safety

Stability is another notable feature in choosing your ladder. No matter how solid and easy position adjustable the ladder will be. If it won’t be stable and shake while setting it on stairs and climbing, what can be more dangerous than that.

The anti-slip rubber caps on the legs of the ladder will offer more traction on both even and uneven surfaces and can prevent the ladder’s wobbling.

Individual legs adjustability

All the stair steps don’t have the same distance from step to step. In the United States, 4 inches to 7 or 7¾ inches are the most recommended step distance for stairs. So when you want to set the ladder on the stairs, you have to customize the ladder’s one side leg 4″-7″ to fit it. You have to especially focus on this feature of the ladder. Otherwise, it will be useless to use it on stairs.

Lightweight and portability

You have to take the ladder from job to job and frequently change its direction and configuration. That’s why a lighter ladder is more appropriate than a heavyweight ladder. The ladder should be a combination of lightweight but sturdy and safe.

So, if the ladder is attached with wheels for easy movement, that will be a plus point for you to walk the ladder to take it from one place to another without carrying.


Many people find that the ladder’s treads are not finished smoothly, so they pinch their fingers when standing on it. Moreover, the narrow foot treads are also a hindrance to comfortably standing on the ladder for a prolonged time if needed. In that case, it causes leg fatigue, which is very painful.

So we’ll suggest you check the smooth finishing of the ladder’s treads and wideness. Both of these features ensure your comfort and satisfaction.

Accessories deck

You have required hammers, screwdrivers, pliers, nuts, bolts, paints, and many things to complete your work when climbing the ladder. Seeking help from a person to give these tools decreases your productivity and efficiency. But if there is no space to keep these tools, you have no option than seeking help.

Here the accessories deck will be very convenient for you to boost up your productivity. All the step ladders won’t come with the accessories deck. But if you frequently do such work that needs tools, you should check this feature.


Yes, you have to keep a budget for your ladder because there is a huge price variation. The stair ladder price starts from $200 and reaches $1200. Of course, the expensive ladder will offer you more exclusive features than a chapter ladder. But, you should go with the features that will offer the benefits you need.

You can choose a ladder that price ranges from $300-500 for using it for household purposes. But if you want to use it professionally, you have to spend at least $800.

Here’s How To Use An Adjustable Ladder On A Staircase

You can easily use an adjustable ladder on the stairs because of its multiple heights and individual leg adjustability. There is no rocket science to using it; instead you have to follow some simple steps.

You can use the ladder on the stairs by following two methods, one is the A-frame mode, and another is the extension mode. We’ll discuss both of the methods so that you can follow any mode according to your convenience.

Method 1 – A-frame Mode

If your stair is short or you need to reach the ceiling, using the ladder in A-frame mode is better than the extension mode.

Step 1: Measure your required height

First, measure the height of your stair’s ceiling with a measuring tape that you want to reach because you have to set the ladder’s height depending on it. When measuring, keep in mind your height.

Step 2: Set up the ladder

Now, tab the ladder’s push knob hinge, set its height with A-frame mode and secure its hinge lock. Keep the front two legs of the ladder on the upper stair step. Then, unlock the rock locks or J locks to extend its outer side to bring the ladder’s balance with the lower step.

Once you get the balanced height, secure the locks and set up the back legs on the lower step. While setting the legs, ensure the ladder’s legs have enough room than the edge of the stair step.

Step 3: Ensure its stability and climbing

After setting the ladder, shake it twice or thrice to check if the setting is ok or not. If the ladder won’t flick or move from its position, now it’s ready to climb.

Method 2 – Extension Mode

If your stair wall is too high and you have to reach the upper part of the wall, you should use the ladder in an extension position.

Step 1: Adjust the ladder’s height

This time, you also have to measure the height to adjust your ladder’s height. Adjust the ladder extension height and relock it by opening the hinge lock.

Step 2: Set the ladder

Stand the ladder with the wall by leaning the upper side. Now, place its one side leg on the upper step of the stair and adjust its opposite side legs with the lower step by adjusting its individual leg.

Step 3: Climb the ladder

After setting the ladder on the stair, it’s time to climb it. Always ensure three safety points (keep your two hands and one leg, or two legs or one hand on the ladder.) when climbing.

Frequently Asked Questions

What Is The Life Expectancy Of A Ladder?

First of all, there is no expiration date for a step ladder, so there is no fixed life expectancy. But if you use the ladder by following proper guidelines and taking care of it when storing, it will last approximately 5-6 years with no repairing. If you use the fiberglass ladder with no care it will last around 1-3 years.

Is Fiberglass Or Aluminum Ladder Stronger?

The fiberglass ladder is stronger and more rigid than the aluminum ladder by considering some specific criteria. For example

  • Where the fiberglass ladder can support a maximum of 375 pounds, the aluminum ladder can support a max of 300 pounds for a type 1 ladder.
  • The fiberglass ladder is non-electric conductive, which means it is safe to use for electrical work. On the contrary, the aluminum ladder conducts electricity, so it’s not safe to use this ladder for this purpose.
  • The fiberglass ladder is lighter than the aluminum ladder though its high support.

So it’s good to choose a fiberglass ladder, but that doesn’t mean the aluminum ladder is less useful. The aluminum ladder is easy to set up, change its position, and fold.

Do I Need an Adjustable Ladder While Cleaning Gutters?
