About Deck Planning

Proper planning is essential for a successful decking project. Understanding material requirements helps with budgeting and ensures you have everything needed before starting construction.

Decking Layout Patterns
  • Straight: The most common and easiest pattern where boards run parallel to joists.
  • Diagonal: Boards are laid at a 45° angle to the joists, providing a distinctive look and potentially better strength.
  • Herringbone: A more complex pattern where boards are arranged in a zigzag formation, creating a visually appealing design.
Decking Materials Considerations
  • Always purchase 10-15% extra material to account for waste, cuts, and defects.
  • Consider the span between joists when selecting board thickness.
  • Hidden fasteners create a cleaner look but may cost more than traditional screws.
  • Board spacing allows for drainage and wood expansion/contraction with weather changes.

Introducing the Decking Calculator

The Decking Calculator is a handy tool for anyone looking to build a deck. By simply entering your deck's dimensions and preferences, you can get a clear estimate of the materials you'll need. This includes the number of boards, fasteners, and the total cost of your project. It's designed to make planning your decking project much easier and more efficient.

Easy Input for Deck Dimensions

You start by entering the length and width of your deck. The calculator allows you to specify these measurements in feet. This straightforward input helps in determining the area of your deck, which is crucial for figuring out how many boards you'll need. Inputting the correct dimensions is the first step to a successful decking project.

Choosing Your Decking Boards

Once you have the dimensions, you can specify the type of boards you'll use. The calculator lets you choose the width and length of the boards in inches and feet, respectively. Additionally, you can set the spacing between the boards. This feature ensures you account for drainage and wood expansion during different weather conditions.

Understanding Deck Layout Patterns

  • Straight: Boards run parallel to the joists, making installation simple.
  • Diagonal: Boards are laid at a 45° angle, providing a striking visual effect.
  • Herringbone: This pattern gives a unique zigzag look, enhancing your deck's aesthetic.

Each layout pattern has its own benefits. The calculator helps you choose the best one for your project, ensuring a beautiful finish that suits your style.

Calculating Fasteners with Ease

Fasteners are essential for securing your decking boards. The calculator allows you to select from different types of fasteners, such as screws or hidden fasteners. You can also specify how many fasteners you'll use per board. This information is crucial for calculating both the total number of fasteners needed and the cost for the entire project.

Advanced Options for Precision

The Decking Calculator includes advanced options to fine-tune your results. You can choose how many decimal places to show in your calculations. Additionally, there's an option to display the calculation steps, which is great for those who want to understand how the final numbers were reached. This level of detail ensures that you have all the information you need at your fingertips.

Visualising Your Decking Project

After entering your details, the calculator provides a visual representation of your deck. This helps you see how your chosen layout will look. The visualisation can be a big help in planning your project and making design decisions. It adds an extra layer of confidence to your decking plans.
