Plan Your Project with Our Paving Calculator

Planning a porcelain paving project? Our porcelain paving calculator makes it easy to get accurate material estimates in just a few clicks. Whether you're a homeowner planning a patio, a landscaper installing a terrace, or a contractor working on a rooftop, this free tool helps you calculate exactly how much porcelain paving you’ll need, along with the right substructure components.

By entering a few key details like area size and installation method, you can avoid overordering, reduce waste, and ensure a smoother installation process. Designed to save time and improve accuracy, the calculator takes the guesswork out of planning and helps you budget confidently for your project.

Our porcelain paving calculator is designed to make project planning simple, accurate, and stress-free. With just a few inputs, you’ll receive a tailored breakdown of the materials needed for your specific space.

To get started, choose between wood-effect and stone-effect tiles. These finishes have different tile dimensions, the stone-effect being square and the wood-effect being longer and thinner to more closely resemble wooden boards. You will then be asked to choose the specific finish of your choice to suit your style.

The paving calculator will need your layout dimensions, input the length and width of the area you are intending to pave, ensuring your measurements are in metres.

The calculator will then ask whether you’re installing directly on pedestals or using a joist and pedestal substructure, which affects the materials required for support and spacing.

If you’re using pedestals, you’ll also be prompted to enter the total build-up height — this helps the calculator recommend the correct pedestal size range for your installation.

Once complete, you’ll receive an instant estimate of the number of tiles, pedestals, and any substructure components required. It’s the easiest way to plan your porcelain paving project accurately and efficiently, whether you’re working on a balcony, terrace, patio, or rooftop.

When it comes to planning a porcelain paving project, accuracy matters. Our porcelain paving calculator takes the uncertainty out of the process by giving you a reliable estimate of the materials you need — saving time, reducing waste, and helping you stay within budget.

Manual calculations or rough estimates can lead to overordering, underordering, and delays on site. With our paving calculator, you get tailored results based on your specific layout, tile size, and installation method. Whether you're installing tiles directly on pedestals or using a joist and pedestal substructure, the tool adapts to suit your setup.

It’s especially helpful for projects with complex layouts or raised systems where planning the substructure is just as important as choosing the paving itself. By calculating everything from tile quantities to pedestal sizes, the porcelain paving calculator streamlines your planning process.

Plan smarter, build faster, and avoid surprises with a paving calculator built specifically for porcelain systems.

A stable, well-planned substructure is essential for the long-term performance of your porcelain paving. Depending on your project needs, you can choose between a pedestal-only system or a joist and pedestal substructure.

For most rooftop or terrace installations, pedestals alone can support structural porcelain tiles directly, creating a clean, level finish with built-in drainage and airflow. This system is ideal for projects where the tiles are load-bearing and laid in a grid pattern.

Alternatively, adding aluminium joists between pedestals allows for greater layout flexibility, easier edge detailing, and more precise levelling — especially useful when working with perimeter trims, slopes for drainage, or more complex layouts.

Our porcelain paving calculator factors in your choice of substructure and recommends the correct components based on your installation type and paving area. It helps ensure that all elements, from pedestals to joists, are compatible and correctly sized for your build-up height and project layout.

Choosing the right substructure for porcelain paving doesn’t need to be complicated — the calculator makes it simple and accurate.

When installing porcelain paving on pedestals, knowing your total build-up height is essential. This measurement — from the base surface to the top of the finished paving — helps determine which pedestal sizes are suitable for your project.

Different pedestal ranges are designed to cover specific height intervals, and selecting the wrong size can lead to instability or the need for costly adjustments on site. If you're incorporating joists, the calculator will also factor in their profile height to ensure total accuracy.

Our porcelain paving calculator uses your inputted build-up height to recommend the correct pedestal size range and quantity, ensuring your substructure is both level and fully supported. This helps avoid overcomplicated builds and ensures your surface performs as intended.

Porcelain paving brings a refined, contemporary look to outdoor spaces, offering the clean lines and elegant finishes often seen in high-end architectural design. Available in a wide range of colours, textures, and stone- and wood-effect styles, it allows you to achieve a modern aesthetic without compromising on performance.

Beyond its looks, porcelain is incredibly durable, stain-resistant, and virtually maintenance-free — making it ideal for terraces, balconies, rooftops, and patios. Its strength and consistency also make it perfect for raised pedestal systems, giving you greater design flexibility and a flawless, level finish.

Our porcelain paving calculator helps you bring your vision to life, ensuring you order exactly what you need for a seamless and stylish installation.
