How to calculate Countertop Square Footage
To calculate the square footage of countertops, multiply the length by the width in inches and then divide the result by 144. For example, Length x Width ÷ 144 = Square footage of your countertops.
26" x 155" ÷ 144 = 27.98 SqFt
Don't forget to include the backsplash in your calculation for a precise estimate.

How to Measure Countertops: Countertops Measuring Tips
The standard countertop depth is between 25.5 and 26 inches. The cabinet base box is 24" plus the doors, which are about 1", resulting in a total depth of 25". Most cabinet islands are 36" to 48" deep and 60" to 80" long.
The average square footage of kitchen countertops ranges from 40SF to 60SF. The actual kitchen countertop square footage will vary based on the kitchen floor plan and whether you have a breakfast bar or island.
After deciding to fabricate and install your stone project, the next step is to measure your countertops accurately. The following tips will simplify the process and ensure efficiency for you and your granite fabricator.
During the final countertop measurement and templating, an adult decision-maker should be present to discuss options and details.
Clear all items from the existing countertops and store away any breakable or valuable items. For safety reasons, keep children and pets away from the construction area.
To avoid substantial costs, do not estimate countertop sizes based on missing or uninstalled appliances or elements. All appliances, including stoves, refrigerators, and dishwashers, should be present at the job site during measurement. All walls, cabinets, panels, moldings, fillers, and apron/farmhouse sinks must be installed before templating and measuring. Incorrect measurements due to these circumstances may require a new piece to be fabricated.
Ensure that cabinets are plumb and level. Unleveled cabinets can cause the new countertop to crack.
After completing the layout drawing and discussing details and options, you will be asked to sign the Shop Ticket with the final drawing to confirm your choices, such as colors, edges, and overhangs.
Make sure you have the correct sink template, which is typically made of paper or cardboard and included with the sink. The sink will be mounted to the countertop at the job site. If you are unsure about the template or do not have one, ask your granite fabricator to check or make one for you. Sink templates are not required for top-mount sinks, but the sinks should be present during installation. Note that sinks are designed for specific applications; ensure that your chosen sink is compatible with your countertop mounting method.
To calculate the final cost, have the following information ready during countertop measurement:
The color of the stone you are purchasing.
The type of sink you are purchasing.
The type of edge finish.
Whether you will have a backsplash.
Whether you need existing counters removed and disposed of.
