# Vinyl plank flooring calculator

> 14′ × 12′ floor: 168 sq ft plus 10% waste is 10 boxes (20 sq ft each), and 49 ft of trim. Click-together LVP: boxes, trim, transitions and the gaps that matter.

## What to buy (14′ × 12′ floor)

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.

| Buy | Material | How StudSheet counts it | What it is for |
|---|---|---|---|
| **10 boxes** | Luxury vinyl plank (LVP) (20 sq ft per box) | 168 sq ft + 10% for cuts (straight layout) = 185 sq ft ÷ 20 sq ft per box. | Click-together waterproof planks that float over the subfloor. |
| **1 pack** | Expansion spacers ¼″ | Hold the ¼″ gap at every wall while you work. | Hold the gap at walls while you install. |
| **7 pieces** | Quarter-round molding (8 ft lengths) | 49 ft around the room (minus doorways) + 10% for miters. | Covers the expansion gap. Nail it to the baseboard, not the floor. |
| **1 box** | 18-ga brad nails (1¼″) | Into the wall or baseboard — never the floor. | For quarter-round and baseboard. |
| **1 tube** | Painter’s acrylic caulk (paintable) | Top edge of the trim and the miters. | Fills gaps between trim and wall. |
| **1 piece** | T-molding or reducer (matching color) | One per doorway where the plank meets another hard floor. | Bridges to another hard floor at a doorway. |

### 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.

## The steps, in order

> **DIY OK: you can do this yourself with standard tools.** About 7–10 hours of work for this example.

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.

## Tools (17)

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

| Tool | Need | Why |
|---|---|---|
| **Utility knife + blades** | **Must have** | Score and snap planks |
| **Speed square** | **Must have** | Triangle square for marking square and angled cuts on lumber. |
| **Tape measure (25 ft)** | **Must have** | The red boxes every 16″ on the blade are stud spacing. |
| **Carpenter's pencil** | **Must have** | Flat, doesn't roll away, marks rough lumber. |
| **Tapping block** | **Must have** | Protects plank edges while you tap joints tight. |
| **Pull bar** | **Must have** | Hooks the last plank so you can tap it tight against the wall. |
| **Rubber mallet** | **Must have** | Taps block, tile and planks into place without damage. |
| **Straightedge (6 ft)** | **Must have** | Checks flatness — or use a straight 10-ft board |
| **Jamb (undercut) saw** | **Must have** | Undercuts door casing |
| **Jigsaw** | **Must have** | Notches around vents and pipes |
| **Knee pads** | **Must have** | Flooring and tile are all knees. |
| **Safety glasses** | **Must have** | Every cut, every nail, every time. |
| **Miter saw** | **Must have** | Cuts trim miters |
| **Caulk gun** | **Must have** | Dispenses caulk and adhesive. |
| **Nail set** | **Must have** | Sinks finish-nail heads below the surface. |
| **Brad nailer (18-ga)** | Rent | Or hand-nail with a nail set |
| **Oscillating multi-tool** | Good to have | Undercuts casing faster than a jamb saw |

## Mistakes and how the math works

### 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.

## Code, permits and safety

The Sheet sets its code notes for the job's state or province. These are New Jersey's and Ontario's; the [code reference](https://studsheet.com/codes) 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.
