How to Lay Out
Tile and Choose a
Starting Point
Laying out tile requires measuring dimensions, snapping reference lines, dry-laying, and checking border cuts. The choice of starting point — center of room (ideal for square rooms), doorway entry (clean look at main view), or focal point (aligned to sinks and ranges) — determines cut layout and aesthetics. Use the tile layout planner to test each starting point visually.

Choosing Your Starting Point
Backsplash setups center on features; entry floors align to doors. Compare starting locations to plan your cuts correctly.
Center Start
Best For
Square rooms, open-plan floors, large entryways.
Why It Works
Ensures border cut tiles are perfectly balanced and equal on opposite walls.
How to execute
Find room center, snap horizontal and vertical plumb lines, dry-lay along both axes, adjust centerline to avoid slivers.
Doorway Entry Start
Best For
Hallways, small bathrooms, rooms with single primary entry.
Why It Works
Guarantees a clean, uncut row of tiles at the main visible entrance line.
How to execute
Start layout directly along the entry line. Push all border cut tiles to the back wall where they are hidden by cabinets or vanity.
Focal Point Start
Best For
Kitchen backsplashes, shower walls, fireplace surrounds.
Why It Works
Aligns the tile geometry to kitchen sinks, range hoods, or shower doors.
How to execute
Snap a vertical centerline through the center of the sink or cooktop. Lay tiles symmetrically outward from this axis.
Step-by-Step Layout Workflow
Laying out tile correctly before mortar is applied guarantees a balanced pattern. Follow these steps to prepare your layout axes.
Verify Wall Squareness
Measure diagonals of the room corner-to-corner. If equal, the room is square. If off by >1/2 inch, plan cuts to absorb the skew.
Snap the Grid
Snap chalk lines connecting the centers of opposite walls to find the geometric center point.
Perform a Dry Lay
Lay out full tiles along both chalk lines without mortar. Check remaining edge spaces on both sides.
Check for Slivers
If the border cuts are less than 3 inches or half a tile, shift the center chalk line by half a tile to balance.
Account for Grout Joints
Always place plastic spacers between dry-laid tiles. A 1/8" joint across 20 tiles adds 2.5 inches to layout length.
Mark the Wet Start Point
Once balanced, mark the position of your first tile with pencil before mixing mortar.
Direction by Tile Type & Size
Square tiles (12×12, 18×18)
Recommended: Grid or Diagonal
Horizontal grid is standard. Diagonal (45°) creates an open feeling but raises waste to 15%.
Plank tiles (wood-look)
Recommended: Horizontal 33% Offset
Always run planks lengthwise along the longest wall dimension to make the room feel deeper.
Shower wall tiles
Recommended: Vertical Stack
Vertical layout increases ceiling height look and reduces grout lines in the splash zone.
Backsplash subway
Recommended: Centerline horizontal
Center alignment above range or sink is critical for a high-end designer look.
Preventing Sliver Cuts
Always dry-lay a full row of tiles from your starting point. If the final cut against the wall is less than half a tile wide, shift your starting line by half a tile to balance.

Layout FAQs
Answers to common starting point and tile layout questions.
Where do you start laying tile in a room?▼
For square or open rooms, start from the exact center by snapping intersecting reference lines. For rooms with a single entrance (like bathrooms or halls), start along the doorway entry line to ensure a clean uncut row of tile is visible at the threshold. For walls or backsplashes, start centered on a visual focal feature (sink or range).
Should tile layout be centered in the room?▼
Yes, in open rooms or rooms with square layouts. Centering ensures that the border cut tiles on opposite sides of the room are identical in width. If you start with a full tile against one wall, the cuts on the opposite wall will almost always be uneven, skewed, and visually unbalanced.
How do I layout tile on a floor?▼
Find the center of the room by connecting the midpoints of opposite walls with chalk lines. Perform a dry lay of tile along both lines. If the final cut tiles against the walls are less than 3 inches wide, shift the starting line by half a tile to widen the border cuts, then proceed with setting.
Which direction should plank tiles run?▼
Always run plank tiles lengthwise parallel to the longest wall of the room. This makes the space look deeper. In narrow hallways, run planks lengthwise along the corridor to draw the eye forward. Always stagger joints by a maximum of 33% (1/3 tile length) to prevent lippage.
What is a dry layout and is it necessary?▼
A dry layout is laying out a row of tiles with spacers on the floor without using any mortar. It is absolutely necessary — it allows you to verify edge measurements, double-check pattern repeats, check for slivers, and make centerline adjustments before any tile is permanently set.
