Home Siding Calculator & 3D Estimator
The fastest way to get siding measurements is to scan the house instead of measuring it. Take exterior photos with a phone, and Hover returns square footage and linear measurements for siding, trim, windows, and roof, along with an interactive 3D model you can design and estimate from.

How to measure siding by hand
Gathering accurate siding measurements is an important part of home renovation. With Hover's home siding estimator, you'll be well on your way to understanding the precise amount of siding needed for any siding job. This will help estimate siding materials needed and an accurate siding cost estimator. Follow step-by-step instructions below to easily estimate siding.
Rectangular walls
Measure the height of the wall.
Measure the width.
Multiply height by width for the total square footage.
Subtract large openings such as a garage door, and leave small windows and doors in to allow for waste.

Gables and triangles
Measure the width at the base.
Measure the height at the peak.
Multiply the two figures.
Divide by two for the square footage of the triangle.

Other shapes
Break the surface into rectangles and triangles.
Measure and calculate each part.
Add the parts together.
Where a shape does not divide cleanly, use height multiplied by width for a rough figure.

How Hover measures siding from a phone scan
The Hover app keeps you off the roof and saves time. Hover uses smartphone photos of any home to build an interactive 3D model with accurate exterior measurements (roof, siding, trim, etc.). Use the 3D model to see different materials and colors on the home.
Siding materials and cost per square
There are a variety of factors that will determine if the type of siding is good for your house or not. However, for all siding options, siding is measured in “Squares” when estimating siding materials. A ‘square’ is a unit that covers 100 square feet. Add up all of your square footage measurements to get the total and divide by 100 to determine the number of siding “squares” you will need to purchase. Using the total square footage, you can get total cost estimates for each material. Here are a few popular materials you can choose from:
Vinyl
Vinyl siding is a great choice for most homes. It’s low-cost, durable, looks beautiful and the time needed to install it is minimal. So, this is an excellent option for homeowners working with a budget. The cost of vinyl siding is as low as $2 per square foot.
Wood
Wood is beautiful but comes at a higher price and requires periodic maintenance. Wood siding costs can range up to $10 per square foot, not to mention additional costs for staining. This is a great option for homeowners on a larger budget.
Stucco
Stucco is one of the highest cost options at upwards of $30 per square foot, but if well maintained it will last a lifetime. Extra care should be taken when applying Stucco to avoid cracks. The durability is great for homeowners who plan to stay in their home for a long time.
FAQ
Accurate siding measurements help exterior home improvement professionals and homeowners more accurately estimate the quantity of required materials and the cost of the job. With accurate measurements, contractors won’t have to buy more materials mid-job (or figure out what to do with unused materials) – saving time and money for both pros and homeowners.
Yes! The Hover app will do all the complicated work for you. Download the app, take some home photos, and in hours, not days, we’ll deliver accurate measurements to contractors and share the home’s interactive 3D model with homeowners and contractors. No ladders, no tape measures, no math formulas needed.
Hover saves professionals hours taking measurements at the job site and calculating quotes in the office, and it’ll save homeowners time in getting their project planning started. The to-scale virtual 3D model allows pros and homeowners to design and visualize the project before it’s built. Hover’s accurate measurements eliminate manual data entry or calculations and the need to re-measure.
Hover makes collaboration possible. All members of the team (sales, production, installation, etc.) and the homeowner can be on the same page when it comes to the exterior home project. Resources can be allocated more efficiently and work can be completed on time and on budget.
Just snap photos of the exterior of any house with the Hover app and we’ll use our patented technology to calculate square footage and linear measurements for roof, siding, windows, trim and more. We’ll also build an interactive 3D model to help homeowners and pros design projects together. But Hover is more than just a roofing calculator and a 3D model. Professionals use Hover’s platform to estimate jobs, create proposals and contracts, and order directly from suppliers.
