Although we can’t cover every fireplace dimension available, by the time you are finished reading this, you should have a good idea of standard fireplaces, custom fireplaces, how to get proper fireplace measurements, and how to get the right fireplace dimensions for your project.

Size Comparison of Different Fireplace Types

To help you visualize the range of different fireplace sizes, here’s a quick reference table:

This table illustrates the diverse range of fireplace sizes available, from standard indoor units to specialized outdoor options. Let’s delve deeper into these different fireplace sizes.

The Basics of Standard Fireplace Sizes

When discussing different fireplace sizes, we’re primarily referring to fireplace appliances – pre-manufactured units designed for home installation.

These differ from traditional masonry fireplaces built with brick and mortar.

Standard Gas and Wood Fireplace Sizes

Standard fireplace appliances typically range from 24-36 inches in width and 24-29 inches in height.

These dimensions work well for many homes, providing a balanced look and adequate heat output.

The depth of indoor wood-burning or gas fireplace appliances is usually around 16-24 inches.

Standard Electric Fireplace Sizes

Electric fireplaces appliances often have minimal depth, as they’re essentially screens that emit heat and display a flame effect.

This makes them a versatile option among the different fireplace sizes available.

When choosing among different fireplace sizes, remember to consider the surround – the decorative frame encompassing the fireplace.

The surround is typically larger than the appliance itself and can be customized to your preferences.

The Basics of Large Fireplace Sizes

For those seeking more substantial options among different fireplace sizes, large fireplaces offer impressive choices:

1. Traditional Fireplaces: These maintain a square shape but with grander dimensions, typically 30 to 56 inches in height and 36 to 56 inches in width. They create striking focal points in spacious living areas or great rooms.
2. Linear Fireplaces: Characterized by their elongated, rectangular shape, these fireplaces are wider than tall. They range from 18 to 60 inches in height, but their width is the showstopper – from several feet to an impressive 30 feet for custom designs. These are ideal for creating dramatic feature walls or dividing open-concept spaces.

Understanding these different fireplace sizes helps you choose the perfect fit for your home, balancing visual impact with practical heating needs.

What Determines Fireplace Dimensions?

While we’ve discussed standard sizes for different fireplace types, the specific dimensions of your fireplace will ultimately depend on your space and heating needs. To determine the ideal size for your fireplace:

1. Measure the width, length, and height of the room where you plan to install the fireplace (in inches).

2. Calculate the room’s volume by multiplying these measurements.

3. Multiply the volume by 4 to determine the minimum heat output needed for the space.

With this information, consult with Dreifuss Fireplaces to determine which of the different fireplace sizes will generate the correct amount of heat for your space. Whether you’re considering a wood-burning, gas, or electric fireplace, we can help you choose the right size for your needs.

Different Fireplace Sizes Doesn’t Mean More Heat

The size of your fireplace can significantly influence both its visual impact and heating capacity. But…

This is a big “but”… the size does not necessarily equal more heat.

• Small fireplaces (24″-30″ wide): Ideal for compact spaces or as supplementary heat sources. They create a cozy atmosphere without overwhelming the room.
• Medium fireplaces (30″-42″ wide): Suitable for average-sized living rooms, providing a balanced focal point and effective heating, however, some models can actually more the heat outside when unwanted.
• Large fireplaces (42″-56″ wide): Make a dramatic statement in spacious rooms, offering powerful heating capabilities and can move heat to other rooms or outside to allow for 12 month usage.
• Extra-large and linear fireplaces (56″+ wide): Create stunning visual centerpieces in large, open-concept spaces or commercial settings. These models can move heat through a ventilation system to multiple floors, rooms and outside for year round use, even in the summer.

Fireplace Sizes by Fuel Type

Different fuel types often correspond to different fireplace sizes:

• Wood-burning fireplaces: Generally require larger dimensions to accommodate wood and provide proper combustion. Typical sizes range from 24″ to 60″ wide.
• Gas fireplaces: Offer the most flexibility in sizing, available in compact models (24″-36″ wide) up to large statement pieces (30’+).
• Electric fireplaces: Provide great versatility in sizing, with ultra-slim models available for small spaces and large format options for bigger rooms.

Your Wall Space vs Your Fireplace

When choosing among different fireplace sizes, consider your available wall space:

1. Measure the height and width of the wall where you plan to install the fireplace (in feet).

2. Calculate the wall’s square footage by multiplying these measurements.

3. Decide on the fireplace’s placement. Many prefer centering the fireplace on the wall.

For example, if you want a 24″ wide fireplace on a 12′ wall:

• Subtract the fireplace width from the wall width: 12′ – 2′ = 10′
• Divide the remaining space by 2: 10′ ÷ 2 = 5′
• Measure 5′ from each side of the wall to find the center point for your fireplace.

This method works for any of the different fireplace sizes you might choose.

Always consult with one of our Dreifuss Fireplaces Experts to ensure precise measurements and perfect placement.

Linear Fireplace Dimensions

While standard fireplaces tend to be square (or close to it), linear fireplaces offer a deviation from the norm. This is immensely welcome to some people who want to heat a wall with greater length.

These fireplaces are shaped like elongated rectangles.

Key features of linear fireplaces:

• Height: Typically 18-30 inches, with some variation.
• Length: Can range from 3′ to 10′ or even longer for custom designs.
• Placement: Often installed 2′-3′ above the floor, but can also be placed lower to the floor.

Many people install linear fireplaces in the middle of an accent wall.

They look great with any fireplace surround regardless of their shape or size.

When considering a linear fireplace, measure your wall and leave about 2′ on each side for a balanced look.

The flexibility in length makes linear fireplaces adaptable to various room sizes, from modest living rooms to grand commercial spaces.

Remember, while these guidelines help you understand different fireplace sizes, always consult with a fireplace expert for the most accurate advice tailored to your specific space and needs.

Outdoor Fireplaces, Firepits, and Firebowls

When considering different fireplace sizes, don’t forget about outdoor options. These fire features extend living spaces and create inviting outdoor environments, ranging from small, portable units to large, built-in structures.

Outdoor Fireplaces

Outdoor fireplaces typically feature larger dimensions compared to their indoor counterparts. Here are the popular fireplace sizes:

– Width: Usually 48 to 60 inches, with custom designs potentially even larger

– Height: Often include chimneys reaching 7 to 8 feet high for smoke management

The larger size of outdoor fireplaces creates a striking visual impact and provides ample heat for gatherings. Styles vary from sleek modern designs to rustic stone structures, offering versatility in both aesthetics and placement.

Firepits

Firepits offer a more casual option among different fireplace sizes for outdoor spaces:

– Small: 20 to 26 inches in diameter

– Medium: 27 to 32 inches in diameter (most common)

– Large: 33 inches in diameter or larger

Available in wood-burning, gas-fueled, or electric models, firepits come in various shapes to complement different outdoor décor styles.

Firebowls

Firebowls provide a modern, artistic approach to outdoor heating:

– Small: 24-30 inches in diameter

– Medium: 31-36 inches in diameter

– Large: 37 inches and above in diameter

Often fueled by gas or propane, firebowls offer clean-burning flames and can be freestanding or built into outdoor structures.

When selecting among these different fireplace sizes for outdoor use, consider your space, local regulations, and specific needs for heat output and aesthetics.

Fireplace Mantels and Surrounds

The mantel and surround are crucial elements that complement your chosen fireplace size. These components can be customized to match your home’s style, from traditional wood mantels to modern, minimalist surrounds.

Remember that the dimensions of your mantel and surround will be directly influenced by your fireplace size. Depending on the material used, there may be a “minimum distance to combustible materials” set by the manufacturer. When planning your fireplace installation, factor in these additional elements to ensure a cohesive and visually appealing result.

Fireplace Inserts: A Unique Approach to Different Fireplace Sizes

Fireplace inserts offer a way to upgrade existing masonry fireplaces, providing improved efficiency and heat output. When considering fireplace inserts, keep in mind:

1. Sizing: Inserts are generally smaller than standard fireplace appliances, designed to fit within existing masonry fireplace openings.

2. Measurement: Precise measurements of your existing fireplace opening (height, width, and depth) are crucial for proper fitting.

3. Surrounds: Due to size differences, a fireplace surround (or trim kit) is typically necessary to cover gaps and improve efficiency.

Properly Sizing Your Fireplace Insert To Your Masonry Opening

Fireplace inserts come in various sizes to accommodate different fireplace opening types, like brick, stone or block. The fireplace dimension sizes play a major role in determining the proper insert for the project.

There is no “set fireplace size” or “standard fireplace size” in any housing code for a masonry fireplace opening. Generally, masons build fireplace dimensions and chimneys to the size that requires the least amount of cutting or shaping of material.

Masonry Fireplace Sizes

That said, there are a few things that remain the same.

The “standard fireplace dimensions” are usually based on the material used. This means we need to measure the smallest dimension of the opening. For example, if you are trying to find the overall fireplace dimensions of a stone fireplace, it may be more difficult than finding the measurements of a standard brick fireplace with their flat surfaces.

To find the width of a stone fireplace, we would not use the average fireplace width; we would measure the fireplace in many places to find the smallest distance between the rocks on either side.

Rock and stone typical fireplace dimensions can range up to an inch or two in deviation and that is perfectly normal.

Standard Fireplace Dimensions for Inserts

Here is the rule of thumb: Take the height, width and depth of the masonry fireplace opening and subtract 2 inches from each. Generally, this will give you plenty of space to work when sliding the new insert into place. Depending on your fireplace design, fireplace surrounds can be installed to cover any gaps.

Fireplace Inserts are available in wood-burning, gas, and electric models. Benefits include improved energy efficiency, enhanced safety, aesthetic upgrades, and versatility in fuel options.

When exploring different fireplace sizes for inserts, Dreifuss Fireplaces can assess your existing fireplace, help you choose the right size and type of insert, and ensure proper installation for safe and efficient operation.

Important Considerations When Installing Different Fireplace Sizes

When planning to install a fireplace, several crucial factors beyond visible dimensions must be considered.

We’ve designed and installed some incredible fireplaces over the years. The fireplace unit by itself does not tell the full story.

Sometimes, the most unique fireplaces are creatively adapted to give the full fireplace effect to the space.

Understanding the following aspects will help you make an informed decision about different fireplace sizes and ensure a safe, efficient, and enjoyable installation.

Hidden Space Requirements

The visible portion of a fireplace is often just the tip of the iceberg. Many fireplaces, especially vented ones, require significant space behind the wall for proper installation and operation. Some of these are really big fireplaces. This hidden infrastructure can include:

– Venting systems

– Insulation

– Gas lines (for gas fireplaces)

– Electrical components

Ventilation Considerations

Ventilation is critical for fireplace installation and operation. Different fireplace sizes and types have varying ventilation needs:

1. Vented Fireplaces: Require a chimney or venting system to expel combustion gases and bring in fresh air. This includes most wood-burning fireplaces and many gas models.

2. Ventless Fireplaces: Some gas fireplaces are designed to burn efficiently without external venting.

3. Electric Fireplaces: Produce no combustion gases, making them the most flexible option for installation among different fireplace sizes.

For vented fireplaces, proper installation of the ventilation system is crucial for safety and efficiency.

Professional installation ensures that complex ventilation systems not only safely remove combustion gases but also enhance the fireplace’s functionality.

Advanced Ventilation Systems

Modern ventilation systems offer additional benefits beyond basic smoke and gas removal:

– Heat distribution to multiple rooms

– Heat redirection outdoors during warmer months

These advanced systems require careful planning and expert installation, regardless of the chosen fireplace size.

Conclusion: Making the Right Choice Among Different Fireplace Sizes

Selecting the right fireplace size is crucial for both aesthetic appeal, functional heating and “just the ability to curl up and take a nap beside it”.

This guide has explored the wide range of fireplace sizes available, from compact electric units to grand wood-burning hearths, and everything in between.

Key takeaways when choosing among different fireplace sizes:

• Consider your room dimensions and available space compared to the fireplace width, fireplace height, and fireplace depth to find the perfect fireplace dimensions.
• Consider fireplace mantels if you want to hang art or a TV above the fireplace. Remember, a fireplace mantel can be wood, cement or other types of non-combustible material.
• Assess your heating needs and energy efficiency goals. More BTUs does not always mean more heat, and smaller does not always mean less heat.
• Factor in local building codes and regulations. Fire safety is of the highest importance to Dreifuss Fireplaces and the homeowners we serve.
• Think about maintenance requirements and fuel availability.
• Don’t forget about hidden space requirements and ventilation needs

Whether you opt for a sleek linear design, a traditional square fireplace, or a modern insert, understanding the different fireplace sizes and their implications will help you make an informed decision.

Remember, the perfect fireplace not only fits your space physically but also complements your lifestyle and meets your heating needs.
