Construction Calculator

Construction Calculator — your all-in-one planning tool for renovation, DIY projects, and professional construction work. Stop guessing how much material to buy. Get exact quantities in seconds.

■ 11 SMART CALCULATORS
FINISHING MATERIALS: Tiles — pieces, adhesive, grout (3 laying methods, custom sizes). Wallpaper — rolls, paste, accounting for pattern repeat. Laminate Flooring — planks, packs, underlay. Paint — liters, cans, primer (4 paint types, 3 surface textures). Plaster — bags, by type and thickness. Drywall — sheets, profiles, screws, joint compound, tape.
BUILDING MATERIALS: Bricks / Blocks — pieces, mortar, cement. Concrete — volume + full mix breakdown (sand, gravel, water). Foundation — strip, slab, or pile types. Floor Screed — cement-sand, semi-dry, or self-leveling. Roofing — sheets, underlayment, battens, ridge caps, drip edge.

■ SHOPPING LIST WITH PROJECTS
Every calculation can be sent straight to a shopping list, organized by project. Plan a kitchen reno and a garage build separately — no mix-up. Create unlimited projects (Bathroom, Kitchen, Garage…). Add results from any calculator with one tap. Tick items off as you buy them. Add custom items manually (anything you need). Share or export your list to Telegram, WhatsApp, Email, or Notes. Built-in formatted text export with checkboxes.
