This 30 × 40″ (75 × 100cm) extra large stretched canvas is a gallery-wrapped artist canvas built on 380 GSM triple-primed, acid-free cotton, stretched over 38mm deep-edge stretcher bars. It's the largest size in our range — a true flagship canvas for exhibition pieces, grand feature walls and commissions where scale itself is the statement. Built to the same professional-grade construction as every size in the range, it's ready to paint straight away and finished to display on the wall without a frame. Suitable for acrylic, oil and mixed media, with a medium-grain surface that holds fine detail and bold texture alike.

Frequently Asked Questions
Is this the largest canvas you offer?
Yes — 30 × 40″ is the largest size in our entire range, built for exhibition pieces, grand feature walls and any project where the canvas itself needs to make the biggest possible statement.
What is a stretched canvas?
A stretched canvas is cotton cloth pulled taut over a wooden stretcher bar frame and secured at the back. This one comes pre-primed with three coats of acid-free gesso, so it's ready to paint straight away rather than something you prime yourself.
Is this canvas suitable for both acrylic and oil paint?
Yes. The triple-primed 380 GSM cotton surface is suited to acrylic, oil and mixed media, with a medium grain that holds pigment evenly.
Do I need to prime it before painting?
No. It's triple primed with acid-free gesso and ready to paint straight out of the packaging.
Does this canvas need a frame?
No — the gallery-wrapped, staple-free edges are finished to hang as-is. You can still frame it later if you prefer a traditional look.
How should I store the canvas before painting?
Store it flat or upright, away from direct sunlight and humidity, until you're ready to paint.

Getting Started
Materials & Construction
Canvas & priming
100% cotton canvas, 380 GSM, triple primed with acid-free gesso.
Frame & construction
Heavy-duty pine stretcher bars, 38mm (1.5″) deep, joined at the corners with a tongue-and-groove fit for a strong, warp-resistant frame. Canvas is stretched taut and secured at the back of the frame — gallery-wrapped, so no staples are visible from any side.
38mm Deep Edge vs 18mm Standard Edge
Choose 38mm for frameless, gallery-style display and heavier paint application. Choose 18mm if you're planning to frame the finished piece and prefer a traditional, cost-conscious canvas.
