How do I calculate flooring for multiple rooms?

To calculate flooring for multiple rooms, use the 'Add Room' button to create separate entries for each room. Enter the length and width dimensions for each room individually. The calculator will automatically sum the total area needed across all rooms, apply appropriate waste allowances for each material type, and provide a comprehensive breakdown showing area requirements for each room plus the overall project total.

How much waste should I add for flooring?

Waste allowance varies by material type: Vinyl plank requires 5-7% waste, laminate needs 7-10%, hardwood requires 8-12%, tile needs 10-15%, and carpet requires 10-20% waste. These percentages account for cuts, pattern matching, and installation errors. The calculator automatically applies the appropriate waste percentage based on your selected flooring material, ensuring you purchase enough material for your project.

How do I calculate boxes needed?

To calculate boxes needed, check your flooring product packaging for the coverage area per box (usually listed in square feet or square meters). Enter this coverage information into the calculator along with your total project area. The calculator will divide the total area by the coverage per box and round up to the nearest whole box, ensuring you have enough material to complete your project without running short.

Can I calculate different materials in one project?

Yes! The calculator supports multiple materials in a single project. Add separate rooms for different materials using the 'Add Room' button. Each room can have its own material type, waste percentage, and coverage specifications. This is perfect for projects where you're using different flooring types in different areas, such as hardwood in living areas and tile in bathrooms or kitchens.

How do I measure irregular shaped rooms?

For irregular shaped rooms, break them down into rectangular sections. Measure the length and width of each rectangular area, then add them as separate rooms in the calculator. For example, an L-shaped room can be divided into two rectangles. The calculator will sum all the areas and apply waste allowances appropriately. This method ensures accurate calculations even for complex room layouts.

Complete Guide to Flooring Types

Choosing the right flooring for your home can be overwhelming with so many options available. This comprehensive guide covers the most popular flooring types, their benefits, ideal applications, and what to avoid to help you make the best decision for your space.

🏠 Laminate Flooring

What it is:

Laminate flooring is a synthetic multi-layer product made with high-density fiberboard (HDF) core, a printed photographic layer (to mimic wood, tile, or stone), and a clear protective wear layer.

Why choose laminate?

Budget-friendly — cheaper than hardwood or tile
Click-lock planks make it easy for DIY installation
Scratch- and stain-resistant
Comes in endless styles: wood grain, white oak, herringbone, etc.

Best for:Living rooms, bedrooms, hallways

Avoid in:Bathrooms or wet areas (unless labeled water-resistant)

💡 Bonus Tip:Opt for AC4 or AC5 wear ratings for higher durability in busy homes.

💧 Vinyl Flooring (LVP, LVT, and Sheet Vinyl)

What it is:

Vinyl flooring is a waterproof synthetic flooring available in tiles, planks (LVP), or sheets. Luxury vinyl has a rigid core and textured surface, offering realistic wood and stone looks.

Why choose vinyl?

Fully waterproof — ideal for kitchens and bathrooms
Soft underfoot with built-in cushion layers
Durable and quiet — great for kids or pets
Easy to install (click-lock or peel-and-stick options)

Best for:Bathrooms, kitchens, basements, laundry rooms

Avoid in:High-heat areas (like sunrooms without climate control)

💡 Bonus Tip:Rigid Core or SPC vinyl offers better dent resistance than flexible options.

🪨 Tile Flooring (Ceramic & Porcelain)

What it is:

Tile flooring includes ceramic (clay-based) and porcelain (denser, fired at higher temps). Both are durable, waterproof, and ideal for wet areas.

Why choose tile?

Long lifespan (20+ years)
Waterproof and easy to clean
Great for radiant heating
Stain-, fade-, and scratch-resistant

Best for:Bathrooms, kitchens, laundry rooms, patios

Avoid in:Bedrooms or anywhere cold underfoot unless heated

💡 Bonus Tip:Porcelain is denser and better for outdoor or commercial use than ceramic.

🌲 Solid Hardwood Flooring

What it is:

Natural planks of solid wood (oak, maple, walnut, etc.), milled to uniform size. Known for its beauty, value, and long-term durability.

Why choose hardwood?

Premium, timeless appearance
Can be sanded and refinished many times
Boosts resale value significantly
Durable when properly maintained

Best for:Living rooms, bedrooms, dining rooms

Avoid in:Basements, bathrooms, or humid climates

💡 Bonus Tip:Choose prefinished planks to save installation time and avoid strong fumes.

🛠 Engineered Wood

What it is:

A layered wood floor made with a hardwood veneer on top and plywood or fiberboard layers underneath. Looks like hardwood but with improved stability.

Why choose engineered wood?

Less prone to warping with moisture or temperature changes
Often more affordable than solid hardwood
Available in click-lock or glue-down formats
Compatible with concrete subfloors

Best for:Condos, basements, modern homes

Avoid in:High-moisture rooms unless specifically rated

💡 Bonus Tip:Some engineered woods can be refinished — check veneer thickness before buying.

🧵 Carpet

What it is:

A soft floor covering made of woven fibers — nylon, polyester, wool, or olefin — and a cushioned backing. Offers warmth and comfort.

Why choose carpet?

Warm and quiet underfoot
Excellent insulation (thermal and sound)
Safe for kids, especially in bedrooms or playrooms
Available in countless textures, colors, and pile heights

Best for:Bedrooms, stairs, family rooms

Avoid in:Kitchens, bathrooms, or allergy-sensitive homes

💡 Bonus Tip:Choose stain-resistant carpet for high-traffic areas or homes with pets.

🍃 Cork Flooring

What it is:

A natural, sustainable material made from the bark of cork oak trees. Soft and springy underfoot with a warm, organic look.

Why choose cork?

Eco-friendly and renewable
Naturally antimicrobial and insect-resistant
Excellent for standing comfort (e.g., kitchens)
Acts as an acoustic insulator

Best for:Kitchens, bedrooms, offices

Avoid in:Areas prone to standing water

💡 Bonus Tip:Needs sealing to prevent moisture damage over time.

🪵 Bamboo Flooring

What it is:

Technically a grass, bamboo is processed into planks and engineered into strong flooring with a sleek, modern finish.

Why choose bamboo?

Sustainable and fast-growing
Harder than some hardwoods (strand-woven bamboo)
Sleek, clean appearance
Available in click-lock or tongue-and-groove systems

Best for:Living rooms, bedrooms, modern interiors

Avoid in:Bathrooms or humid climates

💡 Bonus Tip:Opt for FSC-certified bamboo to ensure eco-conscious sourcing.

⚙️ Concrete Flooring

What it is:

Polished or stained concrete used as a finished floor, often seen in industrial, minimalist, or modern design.

Why choose concrete?

Extremely durable and low maintenance
Customizable with stains, stamps, or epoxy
Suitable for radiant heating
Seamless and allergy-friendly

Best for:Basements, modern lofts, garages

Avoid in:Bedrooms or homes without thermal insulation

💡 Bonus Tip:Requires sealing and periodic waxing to maintain appearance.

🧼 Linoleum

What it is:

A natural alternative to vinyl, made from linseed oil, wood flour, and cork dust. Durable, biodegradable, and available in vibrant patterns.

Why choose linoleum?

Eco-friendly and made from natural ingredients
Naturally antibacterial and antistatic
Long-lasting with minimal maintenance
Water-resistant (but not waterproof)

Best for:Kitchens, hallways, commercial spaces

Avoid in:Bathrooms or places with standing water

💡 Bonus Tip:Linoleum gets more durable over time — the oxidation process hardens it.

How Flooring Coverage is Calculated

We calculate the total area needed for your flooring project:

Base Area = Room Length × Room Width

Waste Area = Base Area × (Waste % ÷ 100)

Total Area = Base Area + Waste Area

For multiple rooms, we sum all areas and apply waste to the total. We also account for:

Unit conversions (auto-switch between ft/in and m/cm)
Optional box coverage calculations for tile/plank materials
Cost estimates when price per unit is provided
