Polar Grid
What this grid is
A Polar Grid is a set of concentric rings and radial spokes centered on one point. It is a practical guide for radial layouts, dials, badges, mandalas, and circular compositions. Unlike a line grid, it emphasizes angles and distance from the center.
Key parameters
- Ring Mode — Linear uses constant spacing; Log uses geometric spacing so rings spread out or compress toward the edge.
- Rings — Number of circles (or circle-like rings).
- Ring Spacing (px) — Baseline distance between rings; in Log mode it is the spacing near the center.
- Ring Ratio — Log mode only; >1 makes outer rings farther apart, <1 makes outer rings denser.
- Spokes — Number of radial lines (0 makes rings only).
- Rotation (deg) — Rotates the whole grid without changing geometry.
- Edge Shape (%) — Keeps the same center and spoke alignment, but changes the ring edge profile: 0 = circular, 100 = straight polygon edges, -100 = inward concave edges.
Unique highlights
- One control spans three looks: circular rings at 0, spoke-aligned polygon rings at positive values, and inward-concave rings at negative values.
- Log spacing creates a strong sense of depth and focus toward the center.
- Works as both a subtle guide (low opacity) and a bold graphic element (thicker stroke).
Typical use cases
- Clock faces, compasses, and instrument dials.
- Rosettes, seals, badges, and circular labels.
- Radial infographics and “sunburst” style layouts.
- Mandala-style pattern bases and circular UI mockups.
- Alignment guides for logos built around a central mark.
Tips
- For a classic “dial” look, use linear rings with 12–60 spokes and moderate opacity.
- For a “center-focused” look, use log rings with a ratio slightly above 1 (e.g., 1.05–1.20).
- If polygon rings look uneven, increase spokes (more sides gives a smoother polygon).
- If the grid feels too busy, reduce spokes first, then reduce rings.
FAQ
What is the difference between Linear and Log ring mode?
Linear keeps equal distances; Log changes spacing progressively so density varies from center to edge.
What does Edge Shape (%) actually do?
It changes each ring from circular (0) to straight-edged polygons (positive values) or inward-concave edges (negative values), using the spoke count as the side/segment reference.
Can I use rings without spokes?
Yes; set Spokes to 0 for rings only.
Why do I need many spokes for polygon rings?
A low spoke count makes a visibly “chunky” polygon; higher counts approximate a circle.
Is this good for precise angle measurement?
Yes; spokes define equal angular steps, which is great for layout and drafting.
