When it comes to your home, few features are as important as the garage door. Not only does it enhance the curb appeal of your property, but it also plays a pivotal role in ensuring the safety and security of your belongings.

Here I’ll cover everything from measurements and materials to styles and warranties, giving you the knowledge you need to make an informed decision.

Standard Two Car Garage Door Sizes

The standard two-car garage door sizes are 16×7 and 16×8 feet. Some larger vehicles may require an 18×7 or 18×8 foot door. These sizes are designed to allow for two standard-sized vehicles to be parked side by side with comfortable clearance.

When choosing a garage door size, it is important to consider the size of your vehicles and the amount of space you need in your garage. For example, if you have a large SUV and a pickup truck, you may want to choose an 18×7 or 18×8 foot door to ensure that your vehicles have enough room.

It is also important to consider the size of your garage opening. The garage door should fit snugly within the opening, but it should also have enough clearance to open and close properly.

If you are unsure of what size garage door you need, it is always best to consult with a professional garage door dealer. They can help you measure your garage opening and choose the right size door for your needs.

Here are some additional things to consider when choosing a garage door size:

  • The type of vehicles you will be parking in the garage
  • The amount of space you need for storage or work
  • The height of your garage ceiling
  • The size of your garage opening
  • The local building codes

How to Measure for a Garage Door

Now that you’re aware of the common sizes, let’s explore how to measure for a garage door. It’s a critical step in ensuring a perfect fit.

To do this, you’ll need to measure the width and height of the opening. Start by measuring the width of the door from the inside of the left jamb to the inside of the right jamb.

Then, measure the height from the floor to the header. Keep in mind that the dimensions should be precise, as any inaccuracies could lead to a poorly fitted door.

Here is a summary of the steps involved in measuring for a garage door:

  1. Measure the width of the opening from the inside of the left jamb to the inside of the right jamb.
  2. Measure the height of the opening from the floor to the header.
  3. If the opening is not square, measure at multiple points and take the smallest measurement.
  4. If you have an existing garage door, measure the width and height of the door itself, not the opening.
  5. Measure the distance from the top of the opening to the ceiling and the distance from the sides of the opening to the nearest walls.

Once you have all of your measurements, you can provide them to a garage door dealer to help you choose the right size door for your needs.

Types of Garage Door Materials

Once you’ve determined the size, it’s time to consider the materials used for your garage door. The most common materials include steel, wood, aluminum, and vinyl.

Each has its own set of advantages and disadvantages, making it crucial to choose one that suits your specific needs.

Steel doors, for example, are known for their durability and low maintenance. Wood doors, on the other hand, offer a classic, elegant look but require more upkeep.

Types of Garage Door Styles

The style of your garage door can significantly impact your home’s aesthetics. Some popular styles include traditional, carriage house, contemporary, and raised panel.

Traditional garage doors feature simple, timeless designs, while carriage house doors mimic the look of old carriage houses with their swing-out appearance.

Contemporary doors are sleek and minimalistic, while raised panel doors offer a more textured and detailed appearance.

Garage Door Insulation Options

Garage door insulation is a critical consideration, particularly if your garage is attached to your home. Insulated doors can help regulate the temperature inside your garage, making it more energy-efficient and comfortable.

Common insulation options include polystyrene and polyurethane. Polyurethane insulation is generally more effective at providing thermal resistance and soundproofing.

Garage Door Hardware

The hardware of your garage door plays a significant role in its functionality and aesthetics. Hinges, handles, and decorative hardware can add character to your door.

Consider the style of your home when choosing these elements to ensure a cohesive look.

Garage Door Brands

When it comes to garage doors, the brand matters. Reputable brands offer quality and reliability, and they often back their products with strong warranties.

Some well-known garage door manufacturers include Clopay, Amarr, Wayne Dalton, and Raynor. Researching these brands and their offerings can help you make an informed decision.

Garage Door Warranties

Garage doors are a long-term investment, and warranties provide peace of mind. A typical warranty may cover manufacturing defects and, in some cases, even the finish and hardware.

Be sure to read and understand the warranty terms before making a purchase.

How to Choose the Right Garage Door Size for Your Needs

Selecting the right garage door size for your specific needs is crucial. Consider the size of your vehicles, available space, and the aesthetic you want to achieve.

Don’t forget to account for insulation and hardware choices, as they can also impact your decision.

Where to Buy a Garage Door

Once you’ve made your decision, it’s essential to know where to purchase your garage door. You can buy from local dealers, home improvement stores, or directly from manufacturers.

Ensure that the seller provides professional installation services or hire a certified installer.

Tips for Installing a Garage Door

Installing a garage door is a complex process best left to professionals. However, if you’re a seasoned DIY enthusiast, you can find comprehensive installation guides provided by the manufacturer.

Keep in mind that safety precautions and proper tools are essential for a successful installation.


When it comes to selecting the right garage door, understanding the standard two car garage door size is just the beginning.

Consider the materials, style, insulation, and hardware to tailor your choice to your unique needs. Don’t forget to research reputable brands and warranty coverage.

With the right decision, you can enhance your home’s functionality, security, and aesthetics, all starting with the right garage door size.
