1. What is Pitch Circle Diameter For Tile?

Pitch Circle Diameter (PCD) is a measurement used in tiling to determine the diameter of the circle that passes through the center of all tile corners in a polygonal arrangement. It's essential for creating precise circular patterns with tiles.

2. How Does the Calculator Work?

The calculator uses the PCD formula:

Where:

• \( Tile Diameter \) — The diameter of individual tiles (in inches)
• \( Sides \) — Number of sides/tiles in the circular pattern
• \( \cos \) — Cosine trigonometric function

Explanation: The formula calculates the diameter of the circle that will perfectly accommodate the specified number of tiles arranged in a circular pattern.

3. Importance of PCD Calculation

Details: Accurate PCD calculation is crucial for creating symmetrical tile patterns, circular designs, and ensuring proper spacing between tiles in circular arrangements.

4. Using the Calculator

Tips: Enter tile diameter in inches and the number of sides (minimum 3). The calculator will determine the pitch circle diameter needed for your tile arrangement.

5. Frequently Asked Questions (FAQ)

Q1: What is the minimum number of sides allowed?
A: The minimum is 3 sides, which creates a triangular pattern. For circular patterns, typically 6 or more sides are used.

Q2: Can I use this for hexagonal tiles?
A: Yes, the calculator works for any tile shape as long as you know the effective diameter of the tiles.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise. Any variance would come from tile manufacturing tolerances or installation techniques.

Q4: Does this work for irregular tile shapes?
A: For irregular shapes, you may need to use the effective diameter or the longest diagonal measurement of the tile.

Q5: Can I calculate the reverse - find tile size from PCD?
A: Yes, you can rearrange the formula: Tile Diameter = PCD × cos(180°/Sides)
