If you’re planning a home upgrade, windows are one of those projects where the cost can shift significantly depending on the size. Understanding window prices by size provides homeowners with a clearer picture of what to expect before contacting contractors or visiting the store.
If you’re considering replacing windows, size plays a significant role in determining the final cost. Window costs by size typically reflect both the price of the window itself and the cost of professional installation, regardless of the frame material.
| Window size (in inches) | Typical use | Estimated price range |
| Small windows (up to 3′×3′) | Bathroom, laundry room, small bedrooms | $150–$600 |
| Mid‑size windows (up to 5′×5′) | Standard bedrooms, home offices | $300–$1,000 |
| Large windows (>5′×5′) | Living rooms, dining rooms, picture windows | $1,000+ |
| 24″×36″ (6 sq ft) | Small picture window | $120–$300 |
| 30″×36″ | Standard bedroom | $160–$270 |
| 36″×48″ (12 sq ft) | Medium picture window | $240–$600 |
| 36″×60″ (15 sq ft) | Medium/large picture window | $300–$750 |
| 36″×72″ (18 sq ft) | Tall picture window | $360–$900 |
| 48″×48″ (16 sq ft) | Square picture window | $320–$800 |
| 48″×60″ (20 sq ft) | Large picture window | $400–$1,000 |
| 48″×72″ (24 sq ft) | Large picture window | $480–$1,000 |
| 60″×60″ (25 sq ft) | Large picture window | $500–$1,200 |
| 72″×48″ (24 sq ft) | Wide, short picture window | $480–$1,200 |
| 72″×72″ (36 sq ft) | Huge picture window | $720–$1,800 |
| 96″×48″ (32 sq ft) | Panoramic picture window | $640–$1,000 |
| 96″×60″ (40 sq ft) | Panoramic picture window | $800–$2,000 |
| 96″×72″ (48 sq ft) | Wall-sized picture window | $960–$2,400 |
| 96″×96″ (64 sq ft) | Floor‑to‑ceiling picture window | $1,300–$3,000 |
Not every home can be fitted with standard window dimensions. Older houses, unique architectural features, or design preferences often call for custom sizing. In these cases, homeowners can expect window prices to be higher than those of off-the-shelf options. On average, a custom-sized window with professional installation ranges from approximately $500 to $1,200 per unit; however, larger or uniquely shaped windows can easily exceed $2,000.
For specialty projects, such as those with curved or oversized openings, the cost of large windows can increase significantly compared to standard sizes.
When you compare window prices across different styles, the variation can be significant. Each window style has its typical cost range due to differences in design and installation complexity. Below are some common window styles and what you can expect to pay for each:
Single-hung windows are among the most budget-friendly options, with typical prices ranging from about $200 to $600 per window. Only the bottom sash opens, while the top sash remains fixed, making this style low-maintenance and straightforward to operate.
Installed double-hung windows cost roughly $300 to $900 each. In return for a higher price than single-hung windows, they offer two operable sashes (both the top and bottom can slide open) for improved ventilation and easier cleaning. This versatility has made the double-hung window one of the most popular styles in homes.
Sliding windows typically cost between $300 and $1,000 per window. These units open by gliding horizontally along a track. They are ideal for wide window openings and have a simple design, though only half of the window can open at once (limiting ventilation compared to hung or crank-operated windows).
Installing casement windows typically ranges from approximately $350 to $1,500 per window. This style is hinged on the side and opens outward with a crank. Casement designs tend to seal very tightly when closed, offering excellent energy efficiency and ventilation control, which can justify their higher cost compared to sliding or hung windows.
Picture windows (large fixed-pane windows that do not open) usually cost between $600 and $2,500 per window. Because they have no moving parts, picture windows provide expansive views and high insulation value. They often cost less than operable windows of similar size and shape, but keep in mind they won’t provide ventilation.
Bay windows, which feature three panels projecting outward, typically come with a higher price point, ranging from $1,200 to $4,500 for a complete bay unit. Bays create extra interior space and allow more light into a room. However, their design requires additional structural support and more labor to install, so bay windows are more expensive than flat windows of comparable size.
Bow windows are a variation of the bay design, typically costing between $1,500 and $6,000 to install. A bow window uses four or more panels joined at gentle angles to form a wide, curved outward projection. Because bow windows span a larger opening and involve more glass panels and framing, they rank among the costliest window styles to purchase and install.
In addition to the window itself, homeowners also pay for installation. This is usually a fixed window cost, charged per window. Most projects fall within the range of $100 to $500 per window. Easy jobs on ground-level windows are generally cheaper, while more complex installations, such as those involving larger openings or upper floors, cost more.
For big-ticket projects, some contractors also offer window financing, which can help spread out costs over time instead of paying everything at once.
Tackling window installation yourself can be tempting if you’re handy and want to save on labor. The appeal is clear: you control the pace, and the cost is lower upfront. However, the risks are just as real.
An uneven fit or poor sealing can lead to drafts, leaks, and even long-term damage that cancels out any savings. Hiring a professional, while more expensive, brings peace of mind. You’re paying not just for skill but often for a warranty, which can be worth far more than the initial savings. If something goes wrong later, most contractors also handle follow-up window repair as part of their service.
Beyond size, a few key details make the most significant difference in the cost of new windows.
More panes mean higher cost and better insulation. Single-pane is the cheapest but inefficient. Double-pane is the standard balance of price and energy savings. Triple-pane windows are the most expensive option but offer the best comfort in extremely hot or cold climates.
The material used to make the window frame will significantly influence the cost. Vinyl is the most affordable and low-maintenance. Wood costs more and requires regular upkeep, but it has a classic, timeless look. An average vinyl-frame window typically costs $200 to $800 per unit installed, whereas a comparable wood-frame window can range from $300 to $1,500 or more.
Retrofitting (installing a new window into an existing frame opening) is usually much cheaper, typically ranging from $100 to $300 per window. Full-frame replacement involves removing the old frame down to the studs and installing everything new.
Full-frame installations require more labor and materials, with costs typically ranging from $180 to $1,500 per window for the additional work and reconstruction.
Replacing several windows at once usually lowers the cost per unit. Installers often offer bulk discounts, and it’s faster for them to complete one large job instead of multiple small ones.
Window replacement can put a dent in your wallet, but there are clever ways to cut down on the total expense:
Replacing windows is a significant project, and the cost can vary substantially depending on the size, style, and the manner in which the installation is handled. Bigger or custom windows will increase the price, but simple steps — such as comparing a few quotes, inquiring about rebates, or scheduling the work during a slower season — can help keep your budget in check.

Most homeowners pay between $300 and $800 per window, including installation. Costs rise with premium materials, complex styles, or larger sizes.
Bay and bow windows are typically the most expensive, often ranging from $1,200 to $6,000 per installed unit, due to their size and the additional structural work required.
A standard 3′ x 5′ (36″ x 60″) window typically costs between $300 and $750 to install, depending on the frame material and style.
In general, yes. Bigger windows use more glass and require more labor. Design also matters, as some small specialty windows can be more expensive than standard, larger ones.
Yes, most quotes bundle the cost of the window with the cost of professional installation. Always confirm with your contractor to avoid surprises.
Prices can fluctuate significantly depending on size, but understanding window prices by size provides a solid starting point. With a clear understanding of the typical costs for different sizes, you’ll be better equipped to plan, budget, and select the windows that best suit your home.
