Why Stretched Canvas Loses Tension Over Time... A stretched canvas can look perfect today— and loose a few years later. Not because it was damaged. Because tension changes over time. Canvas is a fabric-based material. As temperature, humidity, gravity, and environmental conditions change, the canvas naturally expands and contracts. Over time, that movement can create: • Ripples and surface waviness • Corner looseness and sagging • Distortion across large canvases • Reduced visual presentation quality Many people assume the canvas is failing. In reality, the tension system is changing. This reveals something critical: A canvas isn't just artwork. It's a structural system. At Picture Worth Custom Framing, we evaluate canvas condition, stretcher integrity, environmental factors, and long-term display conditions to help maintain proper presentation. Because preserving a canvas isn't just about protecting the image— it's about protecting the structure holding it.
