Window Prices by Size

One of the most significant elements impacting the cost of replacement windows is what size they are. As you’d expect, the larger the window, the more it tends to cost. A bigger window needs a bigger frame, more glass, and more labor hours to install. On this page, we take an in-depth look at window prices by size, including average costs for small, medium, and large windows as well as what your frame material, glass type, and window type will cost depending on what size you choose.

Average Window Price by Size

Several factors in addition to window size will influence cost, but here is a general look at where average costs fall (not including installation) so you can get a sense of window cost by size.

Small Windows

• Up to about 2×3 feet

These windows are often found in bathrooms or basements. Prices can range from $100 to $400 per window. Small, fixed windows (like picture windows) or single-hung windows will be at the lower end, while high-quality materials or specialty glass will be at the higher end.

Medium Windows

• From about 3×4 to 4×6 feet

Standard sizes for bedrooms and living rooms usually fall into this category. Prices can range from $200 to $800. Double-hung and casement windows are common choices for these sizes, with costs increasing for better materials and features.

Large Windows

• Larger than 4×6 feet

These include large picture windows, bay windows, or custom sizes designed for specific spaces. Prices can start at $700 and go up to $3,000 or more, especially for custom designs, high-end materials, or windows that offer advanced energy efficiency or noise reduction features.

What to Know About Window Size

There are standard window sizes produced by multiple manufacturers. However, each type of window comes in its set of standard sizes. For example, double-hung window sizes fit rough openings of 24 to 48 inches wide, whereas picture window sizes fit rough openings up to 96 inches wide.

The difference in standard sizes comes from how the window functions. A double-hung window is designed to be opened vertically, so anything wider than 48 inches may make for especially heavy sashes that are more difficult to operate. A picture window, on the other hand, doesn’t open at all, so it can come in much larger sizes without impacting performance.

You can visit our guide to standard window sizes to learn more about what typical sizes your window type is available is or visit our window replacement page to see all your options for window types, costs, and brands.

Window Type Cost by Size

Single-Hung

Single-hung windows have one sash that opens vertically. They are among the most affordable window types, and they are a good choice for any areas of your home where you want to promote airflow. You can read our guide to single-hung windows to learn more about them, or you can explore our single-hung window cost page for more information on pricing.

Double-Hung

Double-hung windows are the most common window found in homes across the U.S. They open vertically from both the top and the bottom. Having two moveable sashes makes them an excellent choice for ventilation for any room and floor of your home. Our guide to double-hung windows can tell you more about this window type. Our double-hung window cost guide provides specific information on what you can expect to pay.

Sliding

Sliding windows open horizontally instead of vertically, and they are another one of the most popular window types. The variety of sizes they come in makes them a good choice for small or unusually shaped spaces where you need ventilation, like kitchens and bathrooms. Check out our guide to sliding windows to learn more, or visit our sliding window cost page to learn more about what they cost.

Casement

Casements windows are quickly gaining popularity. Instead of opening upwards, they open out. This not only allows more air to come in, but it also means the window glass is uninterrupted by a sash, leaving you with a clear, beautiful view. Read our guide to casement windows to see if this may be the best window type for you, or read up on casement window cost for pricing information.

Picture

Picture windows do not open, meaning this is fixed window type as opposed to an operable one. They come in a huge variety of sizes, and since there are no moving parts to account for, they allow for uninterrupted views of the outside. The lack of moving parts also makes them extremely energy-efficient since there are no areas where conditioned air may leak out or the outside elements may leak in. Learn more about picture windows by reading our guide, or check out our page on average picture window cost for more information on pricing.

Bay

Bay windows protrude out from the home, creating a dramatic exterior effect while also creating extra interior space. While this tends to be one of the most expensive window types, you can find small bay windows for a kitchen or bedroom that may fit into your budget. And, of course, large bay windows for living areas or dining rooms are available from many manufacturers. Our bay windows guide can tell you more about them and our bay window cost page breaks down what you should expect to budget for this project.

Frame Cost by Window Size

In addition to the size of the window and the type of window you choose, one of the largest costs in a window replacement comes from what kind of frame you choose. Here’s how those costs breakdown by frame material for small, medium, and large windows.

Vinyl

The most affordable and most popular option, vinyl windows tend to be pretty energy efficient, and they don’t require much upkeep. But they are also not suitable for all climates or all homes. Our guide to vinyl windows goes into more detail about this frame material.

Wood

With their timeless look and feel plus overall durability and energy efficiency, wood windows remain a popular but pricey frame material option. However, they require a lot of maintenance to keep them in good condition. Read our guide to wood windows if you want to know more.

Aluminum

Aluminum windows are very durable and have excellent longevity. They also have a nice, modern look, and don’t need much maintenance or upkeep. However, they are also not as energy efficient as some of the other materials listed here. Our guide to aluminum windows can tell you more.

Fiberglass

Durable and waterproof, fiberglass frames have all the benefits of wood windows without all the maintenance and care. They are quickly gaining popularity. Our fiberglass windows guide can tell you more about this energy efficient option.

Composite

Also called “clad wood,” this frame material has a wood interior and an aluminum or vinyl exterior. They are incredibly energy-efficient and very durable. Read our guide to clad wood windows for more information.

Glass Cost by Window Size

One of the other major factors in how much a window costs is the window glazing you choose, meaning single, double, or triple pane. Here’s how to break that down by size. These prices are for the glass only.

Single Pane

Due to its lack of insulating properties, single pane windows are only suitable for areas like garages, sheds, or other outbuildings. It offers very little protection against the weather and other elements, and so is not suitable for homes.

Double Pane

Most homes in the U.S. use double pane windows. The costs in the table above are an average range of what you can expect to pay for the glass alone. So if you are choosing a double-hung window of average size with double pane glass, you can expect the glass to make up roughly $200 to $400 dollars of the window’s $600 approximate cost. As you can see, glass is the largest material cost in a window replacement.

Triple Pane

Triple pane windows provide the highest level of insulation and energy efficiency. They are particularly effective in very cold climates. Triple pane glass also offers superior noise reduction. The table above shows the price of the glass only for a variety of window sizes. You can see this glass is significantly more expensive than double pane, but it also does a superior job at insulating your home. While you will pay more up front, you will also save more on your monthly utility bills.

Labor Costs by Window Size

Labor costs vary based on how complicated it is to install your new window, the type of window being installed, local labor rates, and whether the installation involves a straightforward replacement or a new opening needs to be created.

• Small windows typically include those that are up to about 2×3 feet. Installations are generally straightforward, making them less expensive.
• Medium windows are around 3×4 to 4×6 feet, a common size for bedrooms and living areas. The labor costs are higher due to the larger size and potentially more complex installation requirements.
• Large windows or specialty windows (like bay, bow, or large picture windows) can require more labor due to their size, weight, and the intricacies involved in ensuring a proper fit and seal. Costs are higher as a result.

Other Factors That Affect Your Cost

• Cost to remove your old window. If your existing window is damaged or otherwise difficult to remove, it will cost more than removing a window in good condition.
• Any damage that needs to be repaired. If gaps have allowed water to leak in, for example, that will need to be addressed before your new window is installed.
• The brand you choose. Some window brands tend to be more affordable while others are more associated with luxury. Check out picks for the best window brands for more information.
• Other window glass upgrades. Choosing impact-resistant glass can add 20% to 30% more to your project while choosing energy-efficient upgrades like low-E glass or gas infill can add another 15%. Where you live and the weather you see will impact what add-ons you should consider for your glass. You can check out our guide to home window glasses for more information about all your options.
