How to Calculate the Perfect Amount of Mosaic Kitchen Tiles

Posted by Mayang on April 28th, 2025

Few things are as frustrating as running out of tiles during a kitchen project—or realizing your tiles are no longer available. When using mosaic kitchen tiles, ordering the right quantity is vital. It’s not just about measuring the wall; cuts, breakage, and pattern needs can affect your calculations. Here’s a simple guide to ensure you order enough kitchen tiles from the start.

Step 1: Measure Your Space Thoroughly

Begin by determining the area you’ll tile. Use a tape measure to capture the height and width of each section where kitchen tiles will be applied. Multiply to calculate the area in square feet:

• Height × Width = Area (sq ft)

For example:

• Wall 1: 10 ft wide × 2.5 ft high = 25 sq ft
• Wall 2: 4 ft wide × 2.5 ft high = 10 sq ft
• Total: 35 sq ft

Measure every section and add them up. Precision here sets you up for success.

Step 2: Handle Obstacles

Kitchens often have irregularities like outlets také, windows, or cabinets. You can either:

• Measure around these and subtract their area.
• Assume a solid wall and order extra (most pros do this).

For small gaps, treating the wall as continuous is simpler. Minor cutouts won’t waste much, and you’ll have spares for errors.

Step 3: Always Order Extra

A common mistake is ordering just enough. Mosaic kitchen tiles need extra for:

• Cutting and trimming
• Breakage during installation
• Pattern alignment
• Future repairs

Follow this rule:

• Add 10% for simple layouts.
• Add 15–20% for complex patterns like herringbone or mixed mosaics.

Example:

• 35 sq ft total area
• Add 15% for a detailed design: 35 × 1.15 = 40.25 sq ft
• Round up: Order 41 sq ft

Having extra tiles is less costly than searching for a matching batch later.

Step 4: Know Your Tile Sheets

Mosaic kitchen tiles are typically sold in sheets, usually 12" × 12" (1 sq ft). For 41 sq ft, you’d need about 41 sheets. Some sheets are slightly smaller (e.g., 11.7" × 11.7"), so check the specs to avoid a shortage.

Step 5: Plan for Patterns

A basic grid is straightforward, but intricate designs like chevron or diagonal patterns mean:

• More cuts
• More wasted tiles

For multi-color or custom designs, order at least 20% extra. Returning unused sheets is better than running out mid-project.

Step 6: Match Lot Numbers

Tile batches can vary in color or finish, which is noticeable with mosaic kitchen tiles. Ensure all sheets come from the same lot number for consistency. If ordering online, confirm this with the supplier to avoid mismatches.

Pre-Order Checklist

• Measure all areas carefully
• Add 10–20% for waste
• Verify sheet sizes
• Confirm same lot number
• Round up your order

A quick double-check saves time and hassle.

Final Thoughts

Ordering the right amount of mosaic kitchen tiles requires careful planning. Measure accurately, include extra, and verify details. With these steps, you’ll create a stunning backsplash and have spare kitchen tiles for future needs. Better to be prepared than caught short.
