Create Custom Exterior Door Sizes with Plastpro’s Trimmable Doors | Plastpro | Plastpro Inc

While there are standard door sizes, there is no one-size-fits-all approach to doors. There are a variety of factors that might affect door size, such as application and the type of door you choose. Depending on your situation, you may also find the need for a custom-size door to fit your entryway. One type of custom door size is created by trimming down a pre-made door. This works especially well for remodeling older homes, providing an affordable and convenient alternative to creating a completely unique, custom door. To determine if this is the best choice for your situation, it’s important to understand custom exterior door sizes, such as when they might be needed and what options are available. 

Reasons for custom exterior door sizes

Standard sizes for entry doors include:

  • Width: 2/0, 2/4, 2/6, 2/8, 2/10, 3/0, and 3/6
  • Height: 6/8, 7/0, and 8/0
  • Thickness: 1 ¾ inches

If you’ve measured your door and it doesn’t match these sizes, you’ll likely need a custom-size exterior door, which is where trimming may come in. Let’s take a look at a few situations where selecting a trimmable door may be the best option for addressing your need for a custom exterior door size.

1. Old homes/replacing an old door

Replacing a door in an older home often means a standard size door will not fit, as older homes were less likely built with standard features. A custom door size is often required when putting a new exterior door in your older home, but unless the entryway is particularly extravagant, this will likely fall closer to a standard size than other custom doors. Therefore, this need may be most easily addressed by selecting a trimmable door and asking a professional to fit it to your space.

2. You want to use the existing door jamb

If you’ve decided you need or want a new front door but want to use the existing door jamb, a custom door might be necessary. In this situation, a trimmable door will allow you to create your own custom exterior door size to continue using the existing door jamb hassle-free—and this will likely cut costs as well.

Plastpro offers custom exterior door sizes

Plastpro’s Trimmable Door Series is a great option for many situations when you need a custom fit. The Trimmable Series is designed to be customizable to the desired width and height of your entryway. The doors in this series can be trimmed up to 1” from each composite stile, ½” from top rail, and 1 ½” from bottom rail. While you might be worried about the door’s integrity after it’s been trimmed, these doors are built with excess material so that trimming does not compromise the door’s structure, full-length lockblock, or Plastpro’s HydroShield Technology in any way. Your door will still be secure and have a fully composite exterior to prevent warping, rotting, and mold and mildew.


Plastpro’s Trimmable Series offers choices from our Oak Door Series and Smooth Skin Door Series with a variety of designs—from classic to contemporary—to accommodate your home’s exterior.
