The types of windows in your house impact its style and function. And since most windows last at least 15-20 years, choosing new ones is a big deal.
If you’re building a house or are ready to replace your windows, the number of choices can be overwhelming. You need something an appropriate size for your space, practical, and with high energy efficiency. But aside from form and function, you have to consider the cost.
If you’re unsure what to install, here’s an overview and average costs of the 18 most common types of windows.

A single-hung window is a tall rectangle with two sashes. The top sash is stationary, and the bottom sash opens vertically for ventilation. Single-hung windows are among the most common types found in residential homes.
Standard widths for single-hung windows range from 24 to 48 inches, and heights range from 36 to 72 inches. Average costs are $275 to $600 per window.
A double-hung window is similar to a single-hung window – a tall rectangle with two sashes. The difference is both sashes open and close. Most double-hung windows have sashes that can tilt in for easy cleaning.
The most common widths for a double-hung window are 24 to 48 inches, and standard heights range from 36 to 72 inches. Average costs are $600 per window, ranging from $200 to $1,200 depending on size, material, and brand.
Casement windows feature one panel (or sash.) They have a side hinge and open outward to the left or right. Most casement windows open through a hand crank. Some versions have a handle instead, which you push to open and pull to shut the window.
The average widths of casement windows range from 17 to 59 inches. Standard heights vary from 17 to 63 inches. You can get a vinyl casement window for $250 – $600, with the average replacement costing $650, including installation.
Sliding windows are wide, rectangles with two sashes that open horizontally. One or both sashes can open, depending on the type. These windows are common picks for basements, over the kitchen sink, and bathrooms.
Standard sliding windows range from 36 to 84 inches wide, and heights vary from 24 to 60 inches. Prices are $150 to $800 per window, depending on size, brand, and frame material.
Bow windows feature 4-6 windows of equal size. They are installed at a slight angle, “bowing” away from the house. Bow windows create a nook inside that many homeowners equip with a window seat.
Bow window sizes range from 42 inches to 120 inches in width, with typical window heights of 42 inches to 78 inches. The average cost is $3,600, but if you’re putting a bow window where one has never been, prices can far exceed this.
Bay windows are a type of projection window featuring 3-5 panels or windows. They have sharper angles than bow windows and protrude further from the home’s exterior wall. A typical bay window setup includes a picture window in the middle and two operable windows, like double-hung or casement, on either side.
Bay window widths range from 36 to 126 inches wide, with heights spanning 36 to 78 inches. The average cost of a bay window is $1,200 to $2,600.
Picture windows are large windows with a low profile frame. The glass on these windows is left bare for unobstructed views. The purpose of picture windows is to act as a frame, displaying views outside.
The most common widths for a picture window are 24 to 96 inches, with typical heights reaching 96 inches. Size is the biggest pricing factor, with costs ranging from $250 to $1,000.
Garden windows are small projection windows with four glass panels, popular over the kitchen sink. They feature a middle glass panel, one on each side and another as a roof. The design emulates a greenhouse, giving homeowners a place to grow houseplants or herbs.
Most garden windows range from 24” x 24” to 72” x 60.” A standard 24” x 36” garden window costs between $2,000 and $3,00.
The typical awning window is a wide rectangle or square with a hinge at the top. These windows open up and outward, most often by using a hand crank. Awning windows are popular for basements, bathrooms, and other tight areas.
Standard awning window widths range from 18 to 48 inches with heights from 12 to 48 inches. An awning window will cost you $300 to $1,000, depending on size, frame material, and brand.
A hopper window is the reverse of an awning window. It has a hinge at the bottom and opens inward and down. It’s another popular choice for tight areas like basements and bathrooms.
Standard hopper window widths are 30-36 inches with heights of 12-24 inches. You can find hopper windows as inexpensive as $100, with prices ranging up to $1,000 depending on size.
There are many types of arch windows. Most have an arch at the top and a rectangle at the bottom. They can come in one big piece but more commonly consist of a regular window with a partial circle on top.
Since there are several variations of arched windows, there’s no standard size. The typical costs range from $275 to $875 per window, including installation.
Round windows are circular, often called porthole windows. They are common for attics, closets, and tight spaces, but most don’t open. Instead, they provide natural light and add a decorative element to a room.
Round windows are 24-36 inches in diameter with costs that start at $200 and go up depending on size, features, and brand.
Jalousie windows feature split slats that open and close in unison by the turn of a crank. The design promotes ventilation and resembles a Venetian blind. These windows peaked in the 1940s – 1960s and fell out of favor when air conditioning became mainstream. Since they are not energy efficient, most manufacturers have stopped making them.
Jalousie windows come in sizes similar to double-hung windows. The average costs range from $200-$400 per window, but they’re harder to find.
Transom windows are small and go atop door frames. They debuted in the 14th century and have been a popular accent window since. Many homeowners place transom windows over entryway and interior doors as a design element and a way to let more natural light in the house.
Transom windows range from a few inches tall to over 36 inches, with standard widths of 15 inches to 96 inches. Costs for transom windows are $150 to $300.
Glass Block Windows
Glass block windows are large panels of thick glass blocks. Many homeowners choose glass block windows for the basement since they’re secure and weatherproof. The biggest con to these windows is they don’t open or feature only small ventilation panels.
Rather than standard dimensions, glass block windows come in various sizes and designs. You can find small glass block windows for less than $100, while large panels are as much as $1,000.
An egress window needs to meet the International Residential Code for fire safety. These windows must be big enough for an emergency exit with a net clear opening of at least 5.7 square feet, a minimum opening width of 20 inches, and a minimum opening height of 24 inches.
Several types of windows can be egress as long as they meet safety codes. Single-hung, double-hung, casement, and sliding windows are the most common.
Skylights are rooftop windows coveted for the natural light and views they provide. Most skylights are fixed, but some can open. With proper installation, these windows can add value to a home and make a room feel bigger.
Skylights come in many sizes and shapes. The average cost of a skylight and installation ranges from $900 to $2,300.
Storm windows go on the interior or exterior of your home over your regular windows. They stop air leaks and increase energy efficiency, most popular for use with older single-pane windows. If you’re interested in storm windows, you can choose from various functionalities and styles.
You can find storm windows in all standard window sizes. They cost, on average, $85 to $180 per window.
When choosing a window style, there are many considerations to make. Aside from the looks of the window, you need to consider how the window functions.
For example, a protrusion or outward opening window may not work if your house is close to another structure. In this case, you’d need window horizontal or vertical opening windows.
