The first time I watched someone frame a finished canvas painting by shoving it into a standard photo frame from the market, the kind meant for printed photographs, I said nothing. The wood cracked slightly at the corner. The canvas sat too deep inside the frame, swallowed whole. The painting looked worse after framing than it did leaning bare against the wall.
That is what happens when you treat canvas framing like a general task rather than a specific one.
Framing an acrylic painting on canvas is not complicated, but it requires you to understand what canvas actually is, a material with depth, with edges, with structure, and match that understanding to the right framing method. Get it right and the painting commands the wall. Get it wrong and no amount of good paint will save it.
This is what I have learned, and what the best frame specialists in Nigeria will tell you if you ask them the right questions.
First: Does Your Canvas Even Need a Frame?
This is a question most guides skip, and they should not.
If your canvas has thick, gallery-wrapped edges, typically 38mm (1.5 inches) or deeper, where the painting continues around the sides, it is designed to hang on its own. Nigerian frame specialists like Branda Nigeria and iPrints Lagos will tell you the same thing: a gallery-wrap is a finished presentation in itself. A frame on top of it is optional, not mandatory.
However, a frame becomes necessary when:
- The canvas edges are raw, unfinished, or stapled visibly on the sides
- The canvas is thin (standard 18mm depth) and the sides show unpainted wood
- You are selling, gifting, or exhibiting the piece and need it to look complete
- The painting is large and needs the structural support a frame provides
If your edges are clean and the painting wraps all the way around, hang it as-is. If they are not, read on.
The Frame Type That Actually Works for Canvas
Most people shopping in Lagos, Abuja, or Port Harcourt go straight to picture frames they can see at a printing shop or on Jiji. The problem is that most standard picture frames, the rectangular frames designed for photographs and paper prints, were not built for stretched canvas.
Here is why:
| Feature | Stretched Canvas | Standard Photo Frame |
|---|---|---|
| Depth | 18mm–38mm | Very shallow |
| Structure | Mounted on stretcher bars | Designed for flat prints |
| Fit | Requires spacing | Sits too deep or won’t fit |
A stretched canvas has depth. It sits on wooden stretcher bars that can be 18mm, 25mm, or 38mm thick. A standard photo frame has a shallow rabbet, the inner channel that holds the artwork, that was built for flat materials. When you force a canvas into it, one of two things happens: the canvas does not fit at all, or it sits so deep inside the frame that the painting disappears into a hole.
The correct frame for an acrylic painting on canvas is called a floater frame.
A floater frame is built so the canvas sits inside without touching the inner edges, leaving a clean, even gap around it.
A floater frame is built with the canvas’s depth in mind. The canvas sits inside the frame but does not touch the inner edges. There is a deliberate gap, usually between 3mm and 6mm, all the way around between the edge of the canvas and the frame. This gap creates what artists and galleries call the “floating” effect: the painting appears to hover inside the frame, suspended, with a thin shadow visible in the gap.
This is not a style preference. It is the structurally correct way to frame a stretched canvas. Museums use it. Galleries use it. The effect is clean, modern, and, more importantly, it does not fight the painting for attention.
iPrints Nigeria, one of Lagos’s established printing and framing companies, describes their acrylic frames as being built for durability with UV-resistant coatings and polished edges. Hazken Digital, who deliver to Lagos, Port Harcourt, and Abuja, manufactures wooden acrylic frame combinations starting from around ₦24,500. Branda Nigeria similarly offers custom acrylic frames in any size, delivered nationwide.
What this tells you is that the Nigerian market has specialists. You do not have to accept a generic frame that was never designed for canvas. Seek out dedicated framing vendors, not just general print shops.
How to Measure Before You Buy
Before you approach any frame vendor, online or at a physical shop, measure your canvas correctly.
Measure the outer dimensions of the canvas: the width and height from the outermost edge of the stretcher bars. This is your frame size.
Then measure the depth of the stretcher bars, how thick the canvas is from front to back. This is the measurement that determines whether a floater frame will actually fit your painting without the canvas sitting too deep or the frame failing to hold it securely.
Write both measurements down.
Any serious frame vendor will ask for them. If they do not ask, find another vendor.
Choosing the Right Floater Frame
Once you know your measurements, the next decision is material and finish.
Wood floater frames are the most recommended option for acrylic paintings. Solid wood frames, natural, stained, or painted, last the longest, look the most polished, and age well alongside the painting.
- Black wood: works with almost any painting
- Natural timber: suits landscapes and warm tones
- White: ideal for minimalist or abstract work
Metal sectional frames are a budget-friendly option and work for contemporary and abstract paintings particularly well.
| Advantage | Limitation |
|---|---|
| Affordable | Less sturdy |
| Modern look | Not ideal for large canvases |
They are available in black, silver, gold, and white finishes. The trade-off is that they feel less substantial, and for large canvases, anything above 60cm on either side, they may not provide enough structural rigidity.
Acrylic frames, the frameless type made from clear or frosted acrylic sheeting, are increasingly popular in Nigeria. Vendors like Branda Nigeria offer acrylic frames that provide a sleek, polished, frameless look ideal for home, office, or retail use. For an acrylic painting, however, be specific: you want an acrylic floater frame or a frame built with enough depth to hold your canvas, not a flat acrylic sheet designed for photograph prints.
Do not use glass over a canvas painting.
Canvas paintings breathe, the material expands and contracts slightly with changes in temperature and humidity. Glass traps that moisture against the paint surface and can cause damage over time. Floater frames are a top choice because they protect without sealing the painting.
The Framing Process, Step by Step
- Let the paint cure fully.
Acrylic paint feels dry to the touch within hours. That is not the same as being cured. Thick layers can remain soft beneath the surface for days. Wait at least 48 to 72 hours. For heavy textures, wait longer. - Varnish the surface.
Apply a non-yellowing acrylic varnish (matte, satin, or gloss). Use thin, even coats and allow each to dry fully.- Protects against dust and UV
- Enhances longevity
- Should be reapplied every 5–10 years
- Lay the frame face-down on a soft surface.
Use a towel or folded fabric to prevent scratches. - Centre the canvas inside the frame.
Use foam core or cardboard spacers. Playing cards can help maintain even spacing. An uneven gap is visible once hung — and it looks like a mistake. - Secure the canvas.
Use L-brackets, clips, or screws. Tighten evenly. Flat-head screws prevent wall damage. - Attach hanging hardware.
Install D-rings about one-third from the top and thread picture wire through them. - Hang level.
Use a spirit level. Even a slight tilt is noticeable.
The Mistakes That Ruin Good Paintings
- Buying the frame before measuring the canvas depth
- Using a frame designed for photographs
- Framing without varnishing
- Assuming all floater frames are the same depth
Measure first, buy second.
Where to Source Frames in Nigeria
The Nigerian market for proper canvas floater frames has grown. You are no longer limited to general printing shops.
- iPrints Nigeria (Lagos) — canvas framing with UV-printed acrylic frames, nationwide delivery
- Hazken Digital (Lagos) — wooden acrylic frame combinations, delivers across major cities
- Acrylic Frame Nigeria — custom acrylic frames in any size, nationwide delivery
- Jumia — multiple vendors; always confirm rabbet depth
- Jiji — local sellers; useful for inspecting physical samples
When contacting any vendor, provide:
| Requirement | Details |
|---|---|
| Size | Width and height |
| Depth | Stretcher bar thickness |
| Type | Frame for stretched canvas |
A vendor who does not ask about canvas depth may send the wrong product.
A Note on What Frame Colour Does to a Painting
Frame colour is not purely aesthetic. It affects how the eye reads the painting.
- Black: absorbs light and focuses attention inward
- Natural wood: adds warmth and context
- White: creates breathing space
- Gold/antique: adds weight and formality
If the frame is the first thing people notice, it is the wrong frame.
Final Thought
A finished acrylic painting on canvas has already done most of the work. Framing it well is about giving it the context it deserves, not drawing attention to itself, not competing with the paint, and not failing structurally within a year of hanging.
Use a floater frame built for your canvas’s actual depth. Varnish before framing. Let the paint cure. Get the gap even. Use proper hanging hardware.
Do those five things and the frame disappears into the wall, which is exactly what a good frame should do.
