Example Data Table

Use these sample inputs to validate your setup.

Scenario Room (L×W) Rug (L×W) Style Clearance Furniture zone
Patio lounge 16 × 12 ft 10 × 8 ft Centered 1.0 ft 9 × 7 ft
Porch seating 4.6 × 3.2 m 3.0 × 2.0 m Bordered 0.4 m 2.6 × 1.8 m
Walkway runner 520 × 180 cm 420 × 80 cm Runner 20 cm

Formula Used

  • Centered placement: X = (RoomW − RugW) / 2, Y = (RoomL − RugL) / 2.
  • Wall clearance maximum: MaxRugW = RoomW − 2×Clearance, MaxRugL = RoomL − 2×Clearance.
  • Front-legs suggestion: SuggestedW = FurnW + 2×SideBorder; SuggestedL = FurnL + FrontLegDepth + BackBorder.
  • Full-under suggestion: SuggestedW = FurnW + 2×SideBorder; SuggestedL = FurnL + 2×PerimeterBorder.
  • Coverage: Coverage% = (RugArea ÷ RoomArea) × 100.
  • Margins: Left = X, Right = RoomW − (X + RugW), Top = Y, Bottom = RoomL − (Y + RugL).
All calculations assume a rectangular room and rug.

How to Use This Calculator

  1. Measure your patio, porch, or garden room length and width.
  2. Enter your rug size, then choose a placement style.
  3. Set wall clearance and walkway targets for comfort.
  4. Optionally add a furniture zone for seating-based layouts.
  5. Press Calculate to see coordinates, margins, and fit checks.
  6. Download CSV for records, or PDF for sharing.

Room and Rug Proportions

Accurate rug planning starts with the usable floor rectangle, not the outside wall line. This planner treats the space as length × width, then applies a perimeter clearance to keep edges from pinching door swings, planters, and base furniture. A practical target is leaving 150–300 mm (6–12 in) of breathing room on each side for small areas, and 300–600 mm (12–24 in) for larger garden rooms. For outdoor settings, account for mat thickness, threshold lips, and drainage slopes; a small adjustment in clearance can always prevent edge curl and keep doors or screens moving freely.

Clearances and Walkways

Comfort is usually defined by the narrowest path. The calculator checks whether the remaining margins can meet a walkway target, so traffic can move without stepping off the rug or brushing furniture. When a walkway is critical, the best fit is often achieved by centering the rug and letting margins absorb small measurement errors.

Furniture Zone Logic

Seating layouts work when the rug supports the “use zone” rather than the entire room. By adding a furniture zone, you can anchor a conversation set while allowing plant stands and circulation outside the rug. The placement coordinates show where the rug can sit while keeping the zone inside the rug footprint, improving stability and visual cohesion.

Alignment and Visual Balance

Three common strategies reduce guesswork: centered, front-edge alignment, and diagonal/feature alignment. Centered layouts prioritize symmetry, while front-edge alignment can emphasize a view line or hearth. Diagonal placement is useful in square rooms to soften hard geometry; the planner reports the implied rotation clearance so corners do not clash with walls.

Exportable Planning for Install Day

The exported CSV captures inputs, computed margins, and the rug’s corner coordinates for quick tape-marking on site. The PDF summary is suitable for sharing with installers or for revisiting seasonal patio changes. Using consistent units and saving scenarios makes it easier to compare rug sizes before purchase.

FAQs

1) What rug size works best for a small patio seating set?

Choose a rug that fits at least the front legs of chairs and the table, while preserving your walkway target. The planner helps you test multiple sizes and see margins before buying.

2) How do I choose the right wall clearance?

Start with 150–300 mm for compact spaces and 300–600 mm for larger rooms. Increase clearance near doors, planters, or vents. Use the fit checks to confirm you still meet your walkway target.

3) What does the furniture zone option represent?

It represents the footprint you want fully supported by the rug, such as a sofa-and-chairs rectangle. If the zone fits inside the rug, the layout feels anchored and furniture is less likely to rock.

4) Can I place a rug off-center on purpose?

Yes. Use alignment options to bias the rug toward a focal point like a garden view or fireplace. The coordinates and margins show how much offset is created, so you can keep traffic clear.

5) Why do my results show negative margins?

Negative margins mean the rug extends beyond the available floor area after applying clearance or walkway requirements. Reduce rug size, reduce clearance, or adjust the placement style to regain positive margins.

6) How should I verify the plan in real life?

Mark the rug outline using painter’s tape from the reported corner coordinates. Walk the paths, open doors, and move chairs. Save the final scenario and export CSV or PDF for reference.
