So, you’ve decided to add a porch deck to your home, but now comes the big question: “What porch deck size should I get?” Adding a porch deck is a great way to enhance your home’s appeal and enjoy the outside ambiance or nature surrounding your property. However, selecting the right size can be tricky. This decision is more than just numbers—it’s also about creating an outdoor spot that will complement your family’s lifestyle.
In this article, we’ll explain the essential factors to consider when deciding on a deck size, discuss the common sizes, and offer guidance on scaling your deck to your home’s square footage.
Factors to Consider When Sizing a Porch Deck
Purpose of the Deck
Think about what you want to do on your deck. Is it for cozy dinners or perhaps for lounging and sunbathing? If you’re planning to entertain guests, you’ll need more feet of space. For smaller, more intimate settings, a deck with limited square feet will do just fine. Knowing the primary function of your deck helps define the actual size you’ll need.
Available Outdoor Space
How much yard space do you have? A larger deck is lovely, but it shouldn’t overwhelm your garden or lawn. Consider the entire outdoor space so you can balance the deck with the rest of your property.
Budget Constraints
Size impacts cost significantly, as bigger decking projects require more decking boards and materials. Your budget will dictate whether you go for larger decks or a smaller-sized and more cost-effective option.
Home Architecture and Style
A deck should complement the deck design of your home. Your decking design ideas should harmonize with the existing structure, whether it’s modern, rustic, or traditional. This ensures your deck isn’t just an addition but feels like an essential part of your home.
Future Needs
Consider potential changes down the line, like adding a hot tub or needing more room if your family grows. Planning these changes now will help you choose a size that will remain functional in the long run.
Local Deck Building Codes for Compliance
- Permitting Requirements. Before you start the decking installation project, check with your local building department about permits. Some building departments require approval for even the most straightforward deck design, so it’s best to make sure you’re compliant from the start.
- Zoning Restrictions. Zoning laws often include setback requirements, which means your deck has to be a certain distance from the property line or other structures. These rules help maintain privacy and safety, so be sure to take measurements seriously to comply.
- Height Regulations. Deck height can affect the need for railings or added support. Local building codes usually specify how high a deck can be without needing additional safety measures. Understanding these regulations helps keep your deck both legal and safe.
- Safety Standards. Building codes help make sure your deck is safe for everyone. Materials used should comply with regulations for proper spacing of deck boards and stability of deck posts and stairs. This ensures your dream deck not only looks great but is also secure to use.
- Approved Materials. Using the right decking materials isn’t just about style; it’s also about safety and durability. Some areas may have restrictions on certain materials, like chemicals in pressure-treated wood, so it’s important to know what’s allowed in your local area.
What Are the Standard Deck Sizes?
12×12 Deck
A 12×12 deck gives you 144 square feet of space, which is perfect for those with limited outdoor space or a simple lifestyle. This size can fit a small table and a few chairs and will give you a cozy spot to enjoy your morning coffee or an evening read.
If you have a smaller yard, this size will create an inviting atmosphere while still allowing for practical use. It’s a good option for first-time deck owners who want something functional without taking up too much room.
16×16 Deck
Moving up to a 16×16 deck offers 256 square feet, which provides plenty of room for activities without feeling cramped. This size is suitable for hosting small family gatherings or outdoor dinners, making it a favorite among homeowners who like to entertain.
With this extra space, you can easily fit a dining set, grill, and maybe even a couple of loungers. It provides a good balance, offers more freedom in arranging your outdoor space, and works well in medium-sized backyards.
20×20 Deck
For those who have a large yard and love entertaining and welcoming guests, a 20×20 deck might be your best bet. Offering 400 square feet, this larger deck size is like an outdoor living room where you can fit multiple seating areas, perhaps a fire pit, and even an outdoor kitchen.
It’s ideal for those who want to create distinct zones for different activities, like dining and lounging. This lets you indulge in various deck design ideas, making it versatile for changing needs over time.
Custom Sizes
While there are standard sizes, sometimes you need something unique. Custom sizes allow you to design a deck that fits your specific needs and yard space perfectly. Whether it means adding a few extra feet for a hot tub or designing a multi-level deck that flows with the landscape, custom sizes will cater to your lifestyle. Tailoring the size means you get exactly what you want, which can add more value and enjoyment to your home in the long run.
Is a 16×20 Deck Big Enough?
In most cases, a 16×20 deck offers a great balance of space without overwhelming your yard. It’s just the right size for various settings, perfect for placing tables, chairs, and maybe even a cozy little sectional. With proper spacing, this deck size provides flexibility and functionality and can cater well to family gatherings or casual evenings outside.
What Is the Average Deck Size?
The average or standard deck size for a typical residential home is around 300 to 400 square feet. This range offers just the right outdoor space for various activities without taking up too much of your yard space. It’s the sweet spot for homeowners who want a functional yet manageable deck that enhances their outdoor living space. This can be adapted to fit your needs and offers stability and a pleasant outdoor retreat.
