Matje: Material Estimator

Matje calculates construction and renovation materials for rooms, walls, floors, and ceilings.

Enter room dimensions for rectangular or L-shaped layouts in metric meters or imperial feet. Define openings such as doors and windows to subtract their exact areas from wall surface totals.

Material Estimations:

Tiles: Compute tile counts, packaging boxes, adhesive bags, grout quantities, and waterproofing requirements. Select installation patterns including straight, brick bond, diagonal, and herringbone with pattern-specific cutting waste adjustments.

Paint: Estimate paint volumes and can counts across single or multiple coats for primer and finish layers, factoring surface texture and color transitions.

Concrete: Calculate cement bags, sand volume, and aggregate volume based on slab area, depth, and standard mix ratios (1:2:4, 1:1.5:3, or 1:3:6).

Bricks and Blocks: Determine unit counts and mortar materials with joint thickness deductions for standard brick and block dimensions.

Plaster and Render: Compute backing and finishing coat materials across interior walls and exterior facades.

Flooring: Calculate flooring planks, packs, underlayment rolls, and expansion gap allowances.

Drywall: Estimate board sheets, joint compound, and drywall tape for wall and ceiling framing.

Project Features:

Multi-layer calculations: Estimate complete installation stacks, such as tiles with adhesive, grout, and membrane layers.

Regional packaging defaults: Support for 25 kg, 42.6 kg (94 lb), and 50 kg cement packaging standards.

Shopping list: Consolidate required items with whole-package rounding and unit pricing for total cost estimation.

Export options: Save and export project summaries and material lists as formatted PDF documents.

Project comparison: Duplicate projects to evaluate different material options, pattern layouts, or room dimensions.
