Composition Guides

Purpose

Composition Guides are geometric overlays displayed over the artwork canvas. They help artists examine the composition of a Reference and plan the placement of elements in a drawing or painting. The guides can be useful when comparing center axes, diagonals, visual directions, and proportional relationships.

A composition guide is an on-screen visual aid. Choosing one does not change the canvas size, reference-image dimensions, or the artwork itself. These guides do not automatically determine a “correct” composition; they support the artist’s own decisions.

This User Manual chapter explains how to use the controls and choose among the available guides. More detailed discussions of composition theory and artistic applications belong in the separate Art Guides section.

How to use

Open a document and expand Composition Guides in the Studio parameter panel.
Select a guide from the dropdown. Guides are organized into thematic groups.
Use the eye button, Show composition guide, to display or hide the selected guide.
If necessary, change Color to make the guide lines easier to see over the Reference.
For certain golden-ratio guides, additional controls become available as explained below.

You can switch between guides to compare compositional arrangements without modifying the underlying Reference. This selector displays one guide type at a time.

Controls

Guide selection and visibility

Choose a guide type from the dropdown list. Its group headers are navigation aids, not selectable guide types.

The eye toggle, Show composition guide, controls the visibility of the selected overlay. Hiding it does not erase the chosen guide type or its settings.

The color-swatch button changes the color of the composition guide lines. Choose a color that remains legible over the current Reference. This color is independent of the Canvas Grid and Reference Grid line colors.

Orientation is available only for Golden Rectangle and Golden Spiral. It changes the orientation of the selected construction without altering the physical canvas dimensions.

Show construction is available only for Golden Spiral. It displays the geometric construction lines used alongside the spiral. Turning it off leaves the spiral guide itself visible.

Available guides

The following guides are listed in this ARS version, organized by their groups. These descriptions are intended as a quick reference, not as a full course in composition theory.

Basic

Simple and frequently used geometric references for an initial composition check.

Rule of Thirds – Divides the canvas into thirds horizontally and vertically to help assess subject and focal-point placement.
Golden Ratio – Marks compositional reference positions based on the golden ratio.
Center Cross – Displays the horizontal and vertical center axes for checking balance and alignment.
Corner Diagonals – Shows diagonals from the corners to help compare directional relationships.

Shape Compositions

Shapes and curves for considering the arrangement of visual masses and the direction of the composition. Arrows in the names distinguish the guide variants.

Triangle ↑ – An upward-facing triangular layout for arranging major elements around three reference points.
Triangle ↓ – A downward-facing triangular layout offering a different three-point arrangement.
Triangle ← – A left-facing triangular layout.
Triangle → – A right-facing triangular layout.
Diamond – A diamond-shaped construction for comparing central and lateral emphasis.
L-Composition ↖ – An L-shaped guide oriented toward the top-left corner.
L-Composition ↗ – An L-shaped guide oriented toward the top-right corner.
L-Composition ↙ – An L-shaped guide oriented toward the bottom-left corner.
L-Composition ↘ – An L-shaped guide oriented toward the bottom-right corner.
S-Curve ← – An S-shaped guide directed toward the left, useful for examining the movement of the viewer’s eye.
S-Curve → – An S-shaped guide directed toward the right.
C-Curve ← – A C-shaped guide oriented toward the left.
C-Curve → – A C-shaped guide oriented toward the right.
Oval Composition – An oval layout for assessing how the main visual masses fit within a common shape.
Oval + Axes – An oval layout with axes for comparing symmetry and the central alignment.
Concentric Ovals – Ovals sharing a center, useful for studying rhythm and central organization.

Diagonal & Armature

Schemes based on diagonals, intersections, and more complex geometric armatures.

Diagonal Method – A system of diagonal guides for locating possible compositional reference points.
Extended Diagonals – An expanded diagonal construction for studying additional directions and intersections.
Golden Triangle ↘ – One orientation of the golden-triangle construction (↘).
Golden Triangle ↗ – The other orientation of the golden-triangle construction (↗).
Rabatment – A rectangular construction that identifies square-based areas related to a side of the rectangle.
Rabatment + Diagonals – The rabatment construction supplemented with diagonal lines.
Harmonic Armature – A harmonic compositional armature with additional reference lines.
Dynamic Armature Grid – A dynamic armature grid for comparing several related visual directions.

Golden / Phi

Guides and constructions based on golden-ratio relationships, presented in several visual forms.

Phi Grid – A compositional grid based on golden-ratio relationships.
Golden Rectangle – Construction lines for the golden rectangle; orientation can be adjusted.
Golden Spiral – A golden spiral guide with adjustable orientation and an optional construction overlay.

Fibonacci

Geometric structures inspired by the Fibonacci number sequence.

Fibonacci Grid – A geometric grid organized according to the Fibonacci sequence.
Fibonacci Squares – A construction of squares arranged according to Fibonacci sequence relationships.
Fibonacci Spiral – A Fibonacci spiral curve for evaluating the path of attention through the composition.
Fibonacci Spiral + Squares – The Fibonacci spiral together with its supporting square construction.

Dynamic Symmetry

Dynamic symmetry variations based on root proportions from √2 through √8. Each value selects a different construction.

Dynamic Symmetry √2 – A dynamic symmetry construction based on the √2 relationship.
Dynamic Symmetry √3 – A dynamic symmetry construction based on the √3 relationship.
Dynamic Symmetry √4 – A dynamic symmetry construction based on the √4 relationship.
Dynamic Symmetry √5 – A dynamic symmetry construction based on the √5 relationship.
Dynamic Symmetry √6 – A dynamic symmetry construction based on the √6 relationship.
Dynamic Symmetry √7 – A dynamic symmetry construction based on the √7 relationship.
Dynamic Symmetry √8 – A dynamic symmetry construction based on the √8 relationship.

Root Constructions

Geometric root constructions from √2 through √8, focusing on the construction itself.

Root √2 Construction – A geometric construction of the √2 proportion.
Root √3 Construction – A geometric construction of the √3 proportion.
Root √4 Construction – A geometric construction of the √4 proportion.
Root √5 Construction – A geometric construction of the √5 proportion.
Root √6 Construction – A geometric construction of the √6 proportion.
Root √7 Construction – A geometric construction of the √7 proportion.
Root √8 Construction – A geometric construction of the √8 proportion.

Proportional Constructions

Reference constructions for selected rectangular proportions and the double square.

Double Square – A construction based on double-square proportions.
Ratio 2:3 – A geometric reference for the 2:3 proportion.
Ratio 3:4 – A geometric reference for the 3:4 proportion.
Ratio 4:5 – A geometric reference for the 4:5 proportion.
Ratio 5:7 – A geometric reference for the 5:7 proportion.

Practical example

When preparing a portrait composition, begin with Rule of Thirds and examine where the main facial features or focal points fall. Compare that arrangement with Center Cross or a triangular guide. If diagonal movement dominates the image, try Diagonal Method. Switching guides offers different ways to analyze a composition, rather than requiring the artist to follow any one scheme.

Important notes

Guides adapt to the document canvas; they do not alter the canvas proportions or Reference geometry.
Composition Guides are separate from the Canvas Grid and Reference Grid, each with its own visibility setting.
Orientation and Show construction are not universal options. They appear only for the guide types indicated above.
The Composition Guides section is disabled when no document is open.
These are visual aids for evaluation. The final compositional decisions remain with the artist.
