Factors to Consider

outside corners

There are some things to consider when you are buying this material.

Height & Length

The height of the product will determine how much wallboard will be needed to make a transition from one height level to another. If you also need to install an additional product like a pipe or joist that is taller than your wallboard. 

As long as your existing wallboard is up to the standard, then you can use a drywall corner bead.

The product’s length will help you determine how much material you need for your project before buying all of them at once. Longer pieces are more costly, while shorter pieces may not fit your space requirements.

Patterns and Finishes

Patterns and Finishes

Some products come in designs and finishes to make the edges of your room look more presentable. 

However, you may need to check the durability of these materials because they get hits from time to time. Especially when something falls off a shelf or similar things.

Thickness & Weight

Thickness & Weight

Another important consideration when buying corner beads for drywall is thickness. 

If it is too thin, it won’t have enough strength, and it might bend. 

On the other hand, if it’s too thick, it will cause cracking on the edges of the cut piece.

They are typically about 0.25″ deep and 1/2″ wide with a gap of about 1/8″.

The intersections will also have different weights, so a drywall corner bead that’s too thick for the intersection will sag under its weight and fall off.

 A drywall corner bead that is too thin might also hang over time or break off while it’s being removed during renovations.



Drywall Corner bead styles come in many different ways for specific corner conditions or use. 

For example, a drywall corner bead with a corner bracket is suitable for framed corner shelving or other corner conditions where they are unnecessary.

Paper corner bead: A Paper corner bead is a very popular type because they come in different sizes to suit various projects, they are easy to cut and install, and they’re usually relatively inexpensive. 

The main drawback is that they tend to curl up at the edges where the paper laps over itself.

Plastic corner bead: It is usually best when you need to cover more than one corner in a room or even all of the edges for an entire room. 

They come in many different shapes and sizes. 

They can be tricky to install with a small trowel, but they’re more durable than other types of corner beads. 

And if you make mistakes, they can be cut down, filled with spackle, and sanded smooth.

Metal corner bead: A metal corner bead is usually a front-runner in terms of strength and durability, but it can be challenging to handle for beginners. 

Metal corner beads should only be used with thin-set mortar and not self-leveling mud because they don’t bend easily. 

Also, if you have to make adjustments after installation, metal corners are difficult to repair.


One of the essential questions is whether or not you need a drywall corner bead. 

For example, They are usually required when installing drywall corner areas like doorways and windows. 

In contrast, other corner conditions such as framed corner shelving and corner molding do not require drywall corner beads.

Aesthetically Pleasing

Drywall corner beads are aesthetically pleasing because it helps to create a seamless finish. 

In addition, they can be used to cover any gaps that might have been created by installing drywall. 

This is especially helpful when installing sheetrock around protruding objects such as pipes or wires that are sticking out from the ceiling.

Adds Coverage

Drywall corner beads are made to create a seal with drywall and to maximize the area for added coverage. 

They can also be used in areas that require expansion joint compounds, such as around windows and doors or on ceilings where other joints may not work.

The edge along a drywall corner is different from the rest of the area and can crack without something to fill in that space. 

Drywall corner beads eliminate this possibility by creating a seal with drywall and giving it a smooth surface to connect to. 

This helps minimize or eliminate cracking at the edges of drywall.

Drywall corner bead allows more build-up of the joint compound for easier finishing. 

In areas that require a wide, flat plane for finishing, such as around windows and doors or inside corners where two walls meet at a 90-degree angle, use of it is the ideal solution.

A drywall edge is a point where two pieces of material meet or intersect. 

For example, when a panel and ceiling join, a corner bead can create a seal to eliminate the need for an expansion joint. 

Drywall corner beads create a seal that also slows down cracks in drywall, allowing for an even smoother connection between drywall and the ceiling joint.

Money Saver

Many people will argue that it is a waste of money, but I firmly believe that it’s an investment. 

Doing drywall corner beads will save you a ton of money in the long run because they strengthen your walls and stop air leaks.

Adds Strength

It is also beneficial because it can be used to strengthen the joints between walls. 

It can be installed into the drywall to create a professional-looking and smooth exterior for your home.

Easy to Install

Beads around the edges of a ceiling, such as beadboard or quarter round, are easier to install than bolts. 

The main difference is that a drywall corner bead is installed on top of the drywall while a bolt is screwed into the stud.


Corner beads are available at any hardware store in a variety of designs and sizes. First, select a design that matches the bead you want to use around the floor molding. 

If you don’t know what the invention will be, choose one designed for corner beads, these are wider than other corner beads and will be easier to cut.


Why Should I Install Corner Beads?

Corner beads are a great way to give separation and support to your drywall. They work as an insulator, preventing the cracking of your plaster from the various forms of stress that it faces.

These products also work to hide the edge where the two drywalls meet. 

Corner beads help you create a seamless look when installing a drywall, and they are available in many different colors and sizes.

How Do Corner Beads Prevent Air Leaks?

Corner beads prevent air leaks by creating a seal. They’re able to do this because they are slightly wider than corner moldings, so corner beads have the ability to create a more continuous seal.

This seal is important because corner beads help you improve air quality in your home and can inhibit drywall cracks as well.

What is Minimum Size for 3/8″ Beads and 5/8″ Beads?

The 3/8″ beads and 5/8″ beads are meant to be used with two different types of drywall. 

The 3/8″ beads are meant for use with gypsum board, and the 5/8″ beads are used with cement board.

How Far Away Should I Stand When Cutting Drywall Corners? 

Standing between 2 to 6 inches from the corner is fine. You will likely have a few shards of drywall trim on the top of your shoes and around your feet. 

Just bring your shoes through the mess to sweep it up later.

What Kind of Tape Should I Use to Attach My Corner Beads to The Surface or Ceiling Joint?

I would recommend using a thin layer of liquid nails or construction glue on the bead to attach it securely to the corner. 

You can also use drywall screws, but I prefer liquid nails or construction glue if possible.

Can I Paint Corner Beads?

Yes, you can paint them. However, the color should cover the whole drywall corner, including its bottom, so you will not notice any white spots.


The home is the most important place for a family and no one wants to live in an unplanned and sloppy house. In order to maintain the beauty of your house, you need to install everything that can improve the appearance of your home walls.
