Suit construction, defined

Full canvas vs half canvas vs fused

Centi Sartoria chooses a suit's canvas from three methods per order, fused, half-canvas or full-canvas, with production in 14 to 20 working days. How a jacket is built, more than the cloth, decides whether a suit feels designer-grade or cheap. Full canvas floats a layer of horsehair-and-wool canvas through the entire jacket front, so it moulds to the body and holds its shape for years. Half canvas runs that canvas through the chest and lapels only, with the lower front fused. A balance of structure, drape and cost. Fused glues the interlining to the cloth throughout: cheapest and lightest, but it can bubble over time and lacks a natural chest roll. Centi Sartoria builds full- and half-canvas made-to-measure suits in its own Shanghai atelier, factory-direct, in about 14 to 20 working days.

The three constructions, opened up

Our own jacket fronts, photographed before the lining went in. This is the layer the whole comparison is about, and looking at it is the only way to settle the question.

A fused jacket front opened on a stand, white fusible interlining bonded across the entire front panel
Fused The white sheet across the whole front is fusible interlining, fixed to the cloth with heat rather than sewn to it. Nothing floats, so nothing settles into a body over the years, and when the bond eventually fails it shows as rippling that cannot be pressed out.
A half-canvas jacket front opened on a stand, the pale canvas chest piece running through chest and lapel and stopping in a curve above the waist
Half canvas The pale shaped panel is the canvas chest piece. It runs through the chest and the lapel, then stops in a curve above the waist. Below that line the front is fused. That curve is the whole definition of half canvas.
The inside of a full-canvas jacket front, canvas running from shoulder to hem with a dark bridle tape along the lapel roll line
Full canvas The same canvas, carried past that curve and down to the hem. That is the entire difference between half and full: not a better canvas, a longer one. The dark tape running up the lapel is the bridle that holds the roll line.

Ask any supplier to open a front and show you where the canvas stops. It takes ten seconds to look at and no answer can talk around it.

All three of these are full canvas

Full canvas describes what is inside a front. It says nothing about whether a hand did the work, and a good part of the price difference between two full-canvas quotes lives in exactly that gap.

The lapel of a full-canvas jacket showing even, regularly repeating machine pad stitching across the canvas
Machine padded Look at the lapel: rows of pad stitching in an even, repeating chevron. That regularity is the tell. A machine holds the same tension on every stitch, which is what makes it consistent and also what stops it varying the pull to build one particular roll.
A full-canvas jacket front with machine work through the body and hand work at the chest and lapel
Part hand work The middle case, and the one buyers are least often told exists. Machine work through the body, hand work where shape actually has to be built. On most cloth that is where any difference shows, and nowhere else.
The chest and lapel canvas of a jacket padded by hand, the stitch rows visibly irregular in spacing and direction
Hand padded The same area, stitched by hand. The rows wander, the spacing changes, and the tension changes with them. That irregularity is not sloppiness. It is the pull being varied on purpose, and it is the one thing a hand can do here that a machine cannot.

Three garments, one phrase on the price list. When a quote says full canvas, that is the moment to ask which of these three you are being sold, from us or from anyone else.

Glossary

The construction terms a brand or buyer meets when sourcing tailoring.

Canvas (canvassing)
An inner layer of horsehair and wool stitched between the cloth and lining of a jacket front. It gives the jacket structure and lets it mould to the wearer's body over time. "Canvassed" construction, full or half, is the hallmark of a quality suit.
Full canvas
A construction in which the canvas is floated through the entire jacket front, from shoulder to hem, attached by stitching rather than glue. It produces the most natural drape and chest roll, breathes well and holds its shape for years. The most exacting and expensive method.
Half canvas
Canvas runs through the chest and lapels only; the lower front is fused. It keeps the natural roll and breathability where it shows most, at lower cost and weight than full canvas. The practical sweet spot for most quality made-to-measure.
Fused
The interlining is glued (fused) to the cloth with heat and adhesive rather than stitched. Cheaper, lighter and faster to make, but it lacks a natural chest roll and can bubble or delaminate over time, especially after dry cleaning.
Chest piece
The shaped canvas assembly that sits across the chest and shoulder of a tailored jacket. Its quality and how it is attached (floated vs fused) largely determine how the jacket sits and ages.
Pad stitching
Rows of small stitches that attach and shape the canvas to the lapel and chest, building in roll and curve by hand or machine. A sign of canvassed, rather than fused, construction.
Bubbling / delamination
When the glue in a fused jacket fails, the outer cloth separates from the interlining and forms visible ripples or bubbles across the front. It is largely irreversible and is the classic failure mode of cheap fused suits.
Roping
A slight raised roll at the sleeve-head seam, a detail of structured tailoring. Unrelated to canvas type, but often discussed alongside construction when judging how a jacket is built.

Frequently asked questions

Half canvas vs full canvas, what's the difference?

Half canvas runs a layer of horsehair-and-wool canvas through the chest and lapels only, with the lower front fused; full canvas floats that canvas through the entire jacket front, from shoulder to hem, held by stitching rather than glue. Full canvas drapes more naturally and lasts longest; half canvas keeps most of that benefit where it shows, at lower cost and weight, which is why half canvas is the usual sweet spot for quality made-to-measure.

What is half canvas?

Half canvas is a jacket construction in which a layer of horsehair-and-wool canvas is sewn through the chest and lapels only, while the lower front is fused. It keeps the natural chest roll and breathability of a canvassed suit where they show most, at lower cost and weight than full canvas, which is why half canvas is the usual sweet spot for quality made-to-measure.

What is full canvas?

Full canvas is a construction in which the canvas is floated through the entire jacket front, from shoulder to hem, held by stitching rather than glue. It produces the most natural drape and chest roll, breathes well and holds its shape for years. The most exacting and expensive of the three methods.

Full canvas vs half canvas, which is better for a suit?

Full canvas is the more premium construction: it drapes most naturally and lasts longest, so it suits a flagship or structured line. Half canvas keeps most of that benefit in the chest and lapels at lower cost and weight, making it the better value for most quality suits and made-to-measure programs. Both beat fused, which is glued and can bubble over time.

What is the difference between full canvas and half canvas?

In a full-canvas jacket the canvas is floated through the entire front, from shoulder to hem. In a half-canvas jacket the canvas runs through the chest and lapels only, and the lower front is fused. Full canvas gives the most natural drape and longevity; half canvas keeps most of that benefit where it shows, at lower cost and weight.

Is a fused suit bad?

Not necessarily. A well-made fused suit can look sharp when new and costs less. But the interlining is glued rather than stitched, so it lacks a natural chest roll and can bubble or delaminate over time, particularly after dry cleaning. For a designer-grade line, canvassed construction is worth the difference.

How can I tell if a suit is canvassed or fused?

Use the pinch test: pinch the cloth at the lower front of the jacket, near the bottom button, and separate the outer layer from the lining. If you can feel a loose, floating third layer between them, it is canvassed. If the layers feel glued together as one, it is fused.

Which construction should a new suit brand choose?

Half canvas is the usual sweet spot: it delivers the natural roll, breathability and longevity buyers associate with a premium suit, at lower cost and weight than full canvas. Reserve full canvas for a flagship or structured line. Avoid fully fused for anything positioned as designer-grade.
