Enter the dimensions of your area to calculate the square footage and estimated cost. This simple tool estimates the area of a rectangular space and converts it into different units. You can also enter a price per square foot to estimate total cost.
Square footage measures the area of a two‑dimensional surface. In real estate, construction, landscaping, and home improvement projects, knowing the area of a floor, yard or lot is essential for estimating materials and costs. Rather than performing math manually or guessing, a square footage calculator makes the process quick and accurate. As the reference Square Footage Calculator notes, if a surface has an irregular shape it can be broken down into simple shapes and their square footages added together to find the total area【631229439010386†L10-L13】.
Whether you’re planning to paint a house, install flooring, lay sod, or estimate materials for a deck, mistakes in area measurements can be costly. Over‑ordering wastes money, while under‑ordering leads to delays. Our calculator automates the math so you can focus on planning. It handles quantities, multiple unit conversions and cost estimation, eliminating the need for spreadsheets or manual conversion formulas. Because calculations run entirely in your browser, your data stays on your device for privacy.
Our tool focuses on rectangular areas, which covers many common applications such as rooms, gardens and concrete slabs. Enter the length and width in feet and choose how many identical areas you have. The calculator multiplies length by width to get the area of a single rectangle, then multiplies by the quantity. It converts this area into square yards, square meters and square inches using internationally recognised conversion factors. These include 1 square yard = 9 square feet, 1 square meter ≈ 10.76 square feet, and 1 square inch = 0.00064516 square foot【631229439010386†L0-L106】. If you enter a price per square foot, the tool multiplies that by the total area to provide a cost estimate.
The following conversions are useful when working between imperial and metric units or larger land measurements:
Square footage calculations are essential for many home and commercial projects. When painting a house, installers often base quotes on square footage because it indicates the quantity of paint and supplies needed. The Calculator.net explanation notes that primer coverage varies widely, typically between 200–400 square feet per gallon【631229439010386†L127-L131】, which highlights why accurate area measurements are vital. Flooring, whether wood, laminate, tile or carpet, is also sold by the square foot. Knowing the exact area helps you compare costs, choose materials and budget properly. Landscapers use square footage to order turf, mulch and pavers. Even real estate listings and property taxes often reference lot size in square feet or acres.
You can convert other units to feet before entering them. For example, multiply meters by 3.2808 to get feet. Our unit conversion reference provides additional help.
No. The price field is optional. If you leave it blank, the tool simply calculates area without estimating cost.
This tool currently handles rectangular areas. For irregular shapes, divide the space into rectangles, calculate each one separately, and sum their areas as suggested by the reference page【631229439010386†L10-L13】.
The tool uses widely accepted conversion factors: 1 square yard equals 9 square feet, 1 square meter equals 10.76 square feet, and 1 square inch equals 0.00064516 square foot【631229439010386†L0-L106】.
No. All calculations happen within your browser. When you refresh the page or leave it, all input values are cleared.
Calculating square footage is a basic but important step in many projects. Manual computation and unit conversions can be error‑prone and time‑consuming. Our online square footage calculator streamlines the process by letting you enter dimensions, quantity and optional price, then instantly providing area in square feet along with multiple conversions and a cost estimate. Using trusted reference values, such as 1 square yard = 9 square feet and 1 square meter = 10.76 square feet【631229439010386†L0-L106】, ensures accuracy. Whether you’re planning a renovation, landscaping a yard, or ordering materials for a commercial job, this tool helps you make confident decisions and budget accurately.
