Project planner
Plan the whole room floor order before you buy packs
Room flooring estimates should connect the floor covering with packs, underlay, trims, skirting, thresholds, subfloor prep, and fitting cost before the order is treated as finished.

How to use it
Planning before buying
Use this planner to keep the measurements, material list, and quote scope aligned before anyone prices the work.
Why trust it
See how the site is maintained
Read the calculator methodology and editorial policy for the standards behind these pages.
Measure first
Take these measurements once, then reuse them through the calculators so the order, budget, and quote request stay aligned.
- Room dimensions
- Doorways and linked spaces
- Pack coverage
- Underlay coverage
- Skirting or trim run
Planning order
Work through the job in this order so the visible finish, hidden layers, accessories, and cost checks are not priced as separate guesses.
Step 1
Measure each room area
Measure the main room, doorways, cupboards, alcoves, and connected hall sections before deciding whether the layout needs a higher waste allowance.
Open Flooring CalculatorStep 2
Convert area into boxes or packs
Use the exact pack coverage and decide whether to keep a same-batch spare pack before the order goes in.
Open Flooring Boxes CalculatorStep 3
Compare laminate and vinyl routes
Check pack coverage, plank direction, moisture requirements, trims, and waste for the product route you are actually considering.
Open Laminate Flooring CalculatorStep 4
Add underlay and edge trim needs
Underlay, thresholds, scotia, skirting, door bars, and subfloor prep often decide whether the quote is complete.
Open Underlay CalculatorStep 5
Sense-check the installed cost
Compare materials, labour, prep, moving furniture, disposal, and contingency before asking fitters to quote.

Treat this as the first pass at the buying list. Add product names, sizes, grades, and exclusions before sending it for a price.
- Flooring packs or boxes
- Underlay
- Skirting or scotia
- Thresholds and trims
- Adhesive or fitting accessories
- Spare pack allowance
Common mistakes
These are the places where tidy measurement maths often breaks once products, delivery, site access, and labour are involved.
- Using room area without pack rounding
- Forgetting same-batch spare stock
- Missing trims, underlay, and subfloor prep
Brief to send for pricing
Price the same room dimensions, product route, pack allowance, underlay, trims, thresholds, skirting decisions, subfloor prep, waste, doors, disposal, and exclusions.

Ceiling Plasterboard Planner
A ceiling board job can look simple on area alone, but the real list needs board orientation, fixings, jointing, skim, access, waste, and paint checked together.

Tile jobs go wrong when the boxes are counted but the substrate, backer board, adhesive, grout, trims, waterproofing, prep, and labour are not priced clearly.

Decking needs a surface count and a frame count. Boards, joists, screws, supports, trims, rails, steps, and finish choices should be priced from the same deck size.
Practical answers
Short answers for the decisions that usually come up before ordering materials or sending a quote request.
How many flooring boxes should I buy?
Measure the room area, add layout waste, divide by pack coverage, and round up to whole boxes or packs.
Should underlay be estimated separately?
Yes. Underlay rolls or packs rarely match the flooring pack count exactly.
Should I keep a spare flooring pack?
Often yes, especially for laminate or vinyl plank where batch matching and future repairs can be difficult after the product range changes.
