How to measure your kitchen for new worktops

Before installing a new worktop, accurate kitchen measurements are vital. Whether you’re refreshing an existing area or planning a new layout after a renovation or extension, taking the time to understand the space will enable a smooth installation for your worktop fitter.

All Olly London, we rely on precision, ensuring perfect layouts and expertly joined surfaces. Here are some of the steps you can take to measure your kitchen for new worktops.

Kitchen measurement tools

Begin by gathering the right equipment for measuring your kitchen. This includes a sturdy tape measure, notepad and pencil. It’s also useful to sketch a kitchen floor plan to record dimensions as you go.

Measure each wall individually, even if they appear to be the same length. Older homes or renovated spaces may have slight variations that affect how a worktop sits. Always measure at least twice to confirm accuracy. Remember to include the depth of existing cabinets, as worktops should align with the base units for a seamless finish.

If you’re unsure about any structural irregularities, consult with a professional fitter before ordering materials.

Kitchen wall lengths and corner spaces

When measuring for new kitchen worktops, focus on the total run of the kitchen layout. Start from one corner and measure along the wall to the next break point, such as an appliance gap, doorway or end panel. For L-shaped or U-shaped kitchens, break the space into sections and measure each run separately.

Don’t forget to note corner angles and unusual wall shapes, as these can affect how the worktop pieces are joined during the installation. Small errors in corner measurements can create noticeable gaps once the worktop is fitted, so precision is essential.

Sinks, hobs and fixtures

Cut-outs for sinks and hobs must be measured carefully. Check the manufacturer’s installation guidelines for the exact dimensions required for each appliance. Mark the centre point where the appliance will sit, then measure outward to confirm clearance on all sides. This ensures there is enough support material around the opening to maintain strength and stability.

Incorrect cut-out measurements result in costly adjustments or replacement materials, which is why many homeowners prefer professional installation.

Avoid common kitchen measurement mistakes

One of the most common errors is forgetting to account for wall irregularities, tiles and splashbacks that may change the final fit. Many people only measure once or use flexible measuring tools that stretch or bend, affecting the reading. Take your time and record measurements clearly. If possible, photograph your kitchen layout to help communicate the space to your worktop fitter.

Hire a professional worktop fitter

While basic measurements help with planning, a professional installation is the best way to ensure a high-quality finish. As specialists in kitchen worktop installation, Olly London focuses on precise fitting rather than design or supply, securing worktops as neatly as possible. A skilled fitter can also help with joint alignment, sealing and surface finishing, which are crucial for long-term durability and appearance.
