Other tools you may find usefulTile and laminate flooring calculator - calculate the amount of material
The tiles and laminate flooring calculatorcalculates the exact number of ceramic tiles or laminate/vinyl planks needed to cover a floor or wall - taking into account the dimensions of the room, the dimensions of the material, the width of the joint and the recommended allowance for losses.
How to calculate the number of tiles?
Basic formula: Number of tiles = Area (m²) / Area of one tile (m²) × (1 + % stock). But the calculator takes into account more: dimensions of the room minus openings (doors, windows), width of joints/grout (usually 2-5 mm for ceramic tiles), waste resulting from cutting at walls and corners, laying pattern (straight, diagonal, brick - diagonal generates more waste).
Recommended stock for losses
Standard recommendations:Ceramic tiles- 10% stock for straight layout, 15% for diagonal layout (45°) due to greater waste when cutting.Laminated panels- 5-10% stock. For complex shapes of rooms (many recesses, columns) - additional 5%.Large format tiles (60×60 cm+)- 10-12% margin, because an error in cutting one tile "costs" more. Always order in advance - differences in production batches (color, shade) may be visible, and additional purchases are made from a different batch.
Ceramic tiles vs. panels - what to choose?
Ceramic tiles- perfect for the kitchen, bathroom, toilet, terrace. Waterproof, easy to clean, durable (50+ years), scratch resistant. Installation is more difficult and expensive (glue, grouting).Porcelain stoneware- harder than ceramics, frost-resistant, ideal for outdoor use and for rooms with high traffic.Laminated panels- for dry rooms (living room, bedroom, office). Quick installation (click system), warm to the touch, cheaper than tiles. Sensitive to moisture - not for bathrooms and kitchens.Vinyl panels (LVT)- waterproof, for bathrooms and kitchens, imitation of wood or stone, warm to the touch, flexible.
Laying patterns and their impact on consumption
Straight layout (parallel to the wall) - minimal losses, easiest installation. Brick layout (1/2 or 1/3 offset) - elegant, moderate losses. Herringbone arrangement - decorative, 15-20% loss. Diagonal arrangement (45°) - modern, optically enlarges the space, 15% loss. Mosaic arrangement - very decorative, minimal losses (small elements). The calculator takes into account the selected laying pattern when calculating the stock.
Frequently asked questions
How many 60×60 cm tiles do I need for 20 m²?
Area of one tile: 0.6 m × 0.6 m = 0.36 m². Number of tiles: 20 / 0.36 ≈ 55.6 = 56 pieces. With 10% margin: 56 × 1.1 = 61.6 ≈ 62 tiles. Check how many tiles are in the package from the manufacturer and order full packages - you will not pay for a "fraction" of the package.
What joint width should I choose for floor tiles?
Floor joints: for rectangular tiles 30×60 and larger - 3-5 mm. For smaller tiles (metro 10×20) — 2–3 mm. For large-format tiles (120×60+) - 2-3 mm (modern minimalist look). Narrower joints look elegant, but require more precise laying. Take the grout thickness into account in your calculations - 5mm grout on a 30×30 cm tile is 15% of the difference in the number of tiles.
Should I immediately subtract the area of doors and windows from the calculations?
Yes - door openings (width × 0.5 m recess) and window recesses can be subtracted from the total area. However, many calculators do not take into account the complexity of cutting around holes - these cuts generate waste. Therefore, even when counting holes, keep a 10% margin.
How to calculate the number of laminated panels for a 15 m² room?
Manufacturers specify the packaging range in m². Divide 15 m² by the packaging area and add a 10% allowance. Example: package with a range of 1.73 m²: 15 / 1.73 = 8.67 → 9 packages + 10% = 10 packages. Take into account the direction of laying the boards - boards parallel to the longer side visually lengthen the room.
Can leftover tiles be returned to the store?
Most DIY stores (Castorama, Leroy Merlin, OBI) accept returns of unpacked packaging within a specified period of time (usually 14-30 days). Opened packages are usually not returnable. Therefore, order with a reasonable margin - 10% is standard. Save any leftovers for future repairs - the same batch may be unavailable in a few years.
