Vinyl plank flooring calculator

Every line shows the quantity to buy and how StudSheet got it: the spacing, the waste and the package size, so you can check it before the supply house or the quote.

In Canada (4.27 m × 3.66 m floor)

Set to Canada, the Sheet works the job out again for Ontario: metric sizes, bag sizes, the frost depth and the code notes. It doesn't just convert feet to meters. The first lines:

• 10 boxes, Luxury vinyl plank (LVP): 15.6 m² + 10% for cuts (straight layout) = 17.2 m² ÷ 1.86 m² per box.
• 1 pack, Expansion spacers 6 mm: Hold the 6 mm gap at every wall while you work.
• 7 pieces, Quarter-round molding: 14.94 m around the room (minus doorways) + 10% for miters.
• 1 box, 18-ga brad nails: Into the wall or baseboard — never the floor.
• 1 tube, Painter’s acrylic caulk (paintable): Top edge of the trim and the miters.
• 1 piece, T-molding or reducer: One per doorway where the plank meets another hard floor.

1. Read your plank’s install guide — acclimation, underlayment and vapor-barrier rules differ by brand.
2. Pull off any shoe molding. Undercut door casing with a jamb saw.
3. Check flatness with a long straightedge. Fill dips over 3/16″ in 10 ft.
4. Plan rows: room width ÷ plank width. If the last row comes out under ⅓ of a plank, split the difference between the first and last rows.
5. Start in a corner with ¼″ spacers. Click rows together; stagger end joints at least 8″ (6–12″ by brand).
6. Cut: score with a utility knife, snap. Jigsaw for notches.
7. Last row: rip to width, pull it tight with the pull bar.
8. Pull the spacers, install transitions, then trim — nailed to the wall or baseboard, never into the floor.

Must-have tools first, then the ones that help and the ones to rent for the day.

Mistakes that cost a callback or a second trip

• Nailing trim into the floor: It pins the floating floor so it buckles or gaps as it moves. Nail quarter-round into the baseboard.
• No expansion gap: Leave ¼″ at every wall, pipe and cabinet or the floor peaks in summer.
• A sliver last row: Measure first. A 1″ strip at the doorway wall looks sloppy and won’t lock.

What the calculator assumes

• +10% for straight layouts, +15% for diagonal.
• Expansion gap ¼″ at walls (LifeProof, Pergo, Mohawk and Shaw guides).
• Flatness: 3/16″ in 10 ft (Pergo, Mohawk; LifeProof allows ¼″).
• End-joint stagger 6–12″ depending on the brand; we plan for 8″.
• Attached-pad planks: no second underlayment. 6-mil poly over concrete only where your brand requires it.

The Sheet sets its code notes for the job's state or province. These are New Jersey's and Ontario's; the code reference has more. Always confirm with your building department.

• Permits: a job like this usually needs none, but towns set their own rules. Ask your building department if you're not sure.
