How to Choose Deck Size & Shape?

In this post, we’ll walk you through selecting the ideal size and design for your entryway deck while taking utility, neighborhood rules, and property features into account. Discover types of decks that are appropriate for outdoor living spaces in various backyard settings as you explore diverse deck shapes, from ground-level to multilevel designs. Make wise choices to create a usable outdoor space that enhances your home and meets your lifestyle requirements.

Different Types of Decks & How They Suit Your Property

It’s important to choose the perfect size and shape for your deck to ensure that it matches your home and fulfills its intended functions. Understanding the many deck shapes that are available and how they can fit the unique features of your property is the first step in this process.

Ground-Level Decks

For homes with single stories and flat yards, ground-level decks are excellent. They are simple to build and make excellent mudrooms, breakfast areas, and entrances. Depending on the local building standards, these attached decks may not always need railings. But remember, modern metal railings will enhance the look of your deck and keep you safe! 

Traditional post-and-pier foundations, continuous footings, or an existing concrete slab can all support ground-level or elevated decks well. You might experiment with cascading decks down a hill for a distinctive appearance or make patterns to delineate garden zones.

Raised Decks

The steep terrain of a property is ideal for raised decks. They enable access to rooms on higher floors and can address issues with landscaping. Creating tall, graceful supports with slightly elevated structure can be a fascinating design task. With raised decks, safety is a top consideration, and adherence to local building requirements regulating railing height and baluster spacing is crucial.

Multi Level Decks

Multi level decks are made to accommodate sloping ground or naturally terraced settings. They are made up of variously sized and shaped parts joined by walkways or stairs. These more standard attached decks are perfect for lots with slopes since they cascade down a hill, providing various vistas as they go. Multi-level attached decks require considerable planning since they feature intricate constructions that call for careful consideration of steps, steel or glass railings, and other deck materials.

Wraparound Decks

Wraparound decks are constructed along more than one side of a property and frequently have more than one entrance. They are ideal for homes with changing levels of sunshine throughout the day. Wraparound outdoor decks also give families flexibility by allowing areas for both public and private events with a hot tub inside the same building.

Average Deck Size & Dimensions for Your Backyard

The typical size of a backyard deck will vary depending on the available area, the deck project intended uses, and the number of users it will support. Let’s look at some classic types of decks and proportions that can fit nicely in various backyard situations.

Small Decks (6×10 feet)

A tiny attached deck of 6 by 10 square feet can be adequate if you only require a basic dining area for family gatherings. This space is suitable for a table and chairs for a comfortable dining experience.

Medium-Sized Decks (12×16 feet)

A medium-sized wood deck that is 12 feet by 16 feet may accommodate a variety of activities for greater adaptability. This size enables enough seating, a large dining area, and even some additional yard space for outside activities.

Large Decks (20×20 feet or more)

20×20-foot or larger decks provide enough outdoor space for multiple zones if you want to build a huge outdoor living area. You may designate platform decks as specific areas for eating, relaxing, grilling, and entertaining.

What Size Should Your Backyard Deck Be?

The right size for your backyard or detached deck depends on your requirements and intended uses for living space. There are a few key steps to follow to determine the ideal deck size for your home.

Step 1: Define Your Deck’s Functions

Write down all the things you wish to do on your deck. This could involve eating, unwinding, hosting visitors, and more. Assign various areas of limited yard space on the deck to the various activities, making sure to provide enough room for each one, traffic flow, and outdoor furniture.

Step 2: Test the Site

Place the furniture and other items you plan to use on your deck, rope off the area, and think about how it will meet your needs. This will enable you to assess whether the size is adequate for your needs. For maximum comfort and flexibility, provide the space underneath each piece of furniture at least one foot of additional room.

Step 3: Consider Legalities

Learn about local building codes, zoning regulations, deed limitations, and easements before completing your deck plans. It’s crucial to follow these regulations because they may have an impact on the dimensions, positioning, and style of your deck.

How to Choose the Best Deck Size?

Finding the ideal top deck type and size requires balancing practicality and beauty. To make an informed choice of many types of decks, take into account the following advice.

Proportion to House Size

Some architects advise that the deck be either one-third the size of the main floor of the home or roughly the same size as the dining room it adjoins. These are only general recommendations; the main thing to think about is whether the attached deck is big enough to perform the tasks it was designed to.

Catering to Specific Activities

Make sure the over-garage deck size accommodates the particular activities you intend to engage in. It will take more indoor and outdoor spaces than a straightforward eating area to create a comfortable place with a hot tub.

Visual Separation for Incompatible Functions

Use planters, trellises, seats, or other composite decking designs to visually separate the locations if incompatible functions must take place adjacent to one another. As an alternative, think about constructing layers or a T-shaped, synthetic decking, connected by steps or ramps.

What is the Best Size Deck?

The ideal entryway deck size will vary depending on each person’s demands, tastes, and available space. It is crucial to think about the activities you want a small deck to accommodate and make sure there is space for each activity without cramming everything in.

What is the Average Size of Decking?

Based on regional tastes, available space, and desired outdoor living experience, the average size of composite decking might vary greatly. In general, medium-sized decks that are 12 feet by 16 feet or larger are fairly popular and meet a variety of demands.

Keep in mind that selecting the ideal deck size and style is a crucial step in establishing a welcoming outdoor area that improves the curb appeal of your home. Once you have established the right deck measurements, you may look into products to improve the appearance and utility of your deck, such as steel metal railings, steel planters, privacy metal screens, glass railings, and more. Have fun decking!
