2/3 Wall Art Ratio Calculator
The 2/3 wall art rule is one of the most widely used interior design principles for choosing artwork sizes above furniture. Interior designers and art installers commonly recommend artwork that measures approximately two-thirds (66%) of the width of the furniture below it.
This rule creates visual balance between furniture and artwork while preventing walls from feeling empty or overcrowded. It is commonly used when hanging art above sofas, beds, console tables and dining tables.
Wall Art Size Quick Rule
- Artwork width: 60–75% of furniture width
- Spacing above furniture: 15–25 cm
- Gallery hanging height: 152 cm centre point
- Triptych spacing: 5–8 cm between panels
These measurements are widely used by interior designers when planning wall art layouts in modern Australian homes.

How the 2/3 Rule Works in Interior Design
Furniture and artwork should visually feel connected rather than separate elements. When artwork measures roughly two-thirds the width of the furniture below it, the composition creates a strong visual anchor that stabilises the entire room layout.
This rule is particularly effective for large furniture pieces such as sofas, beds and dining tables because it ensures the artwork complements the scale of the furniture without overpowering the wall.
