A4, A3, 30×40cm — works over desk or small wall space
Medium Rooms (15-25m²)
A2, 40×50cm, 50×70cm — focal point above sofa or bed
Large Rooms (25m²+)
60×80cm, 70×100cm, 80×100cm — makes a statement, fills tall walls
Frame Availability
Standard frame sizes (A4, A3, A2, 12×16", 16×20", etc.) are widely available at frame shops and online retailers. Custom sizes like 60×80cm may need bespoke framing, which adds cost.
