One of the most common calls we take at our North York warehouse is from customers who aren't sure which acrylic sheet size to order. They know what they're building, they have a rough idea of the material, but the combination of standard sheet sizes, thickness options, and the reality that Canadian suppliers don't all stock the same formats means the decision isn't always obvious.
This guide is designed to cut through that confusion. For broader purchasing context — cast vs extruded, pricing, and supplier selection — see our complete guide to buying acrylic sheets in Canada. We'll walk through standard sheet dimensions available in Canada, explain how to match thickness to your application, cover color and transparency options, and give you practical guidance on cutting and fabrication. Whether you're ordering one sheet for a DIY project or a pallet for commercial production, the same fundamentals apply.
What Is Acrylic Sheet (and Why Does It Matter for Sizing)?
Acrylic sheet — sold under trade names like Plexiglas, Lucite, and Acrylite, and generically as PMMA — is available in two manufacturing variants that handle differently:
Cast acrylic is made by pouring liquid monomer between glass molds. It has excellent optical clarity, consistent thickness, and machines cleanly. It's the right choice for laser cutting, high-quality signage, and applications where edge quality matters. Cast sheets tend to be sold in slightly less standardized sizes because the casting process allows more dimensional flexibility.
Extruded acrylic is manufactured by pushing molten material through a die. It's more economical, dimensionally consistent across large batches, and works well for applications where machining isn't critical. Extruded sheets are more commonly available in the standard 4×8 and 4×10 sheet formats that are compatible with most cutting equipment.
For most project planning purposes, the difference in size and thickness isn't dramatic — but knowing which type you have matters enormously for cutting and finishing.
Standard Acrylic Sheet Sizes Available in Canada
Canadian suppliers typically stock acrylic in the following standard sheet formats. Note that availability varies significantly by supplier — smaller distributors often carry only the most common sizes, while full-service suppliers like FIDAR System stock a broader range.
| Format (inches) | Metric equivalent | Typical use case | |---|---|---| | 24″ × 48″ | 610 × 1220 mm | Small fabrication, DIY panels, retail | | 36″ × 48″ | 915 × 1220 mm | Medium signs, display panels | | 48″ × 96″ (4′ × 8′) | 1220 × 2440 mm | Most common format — commercial standard | | 48″ × 120″ (4′ × 10′) | 1220 × 3050 mm | Larger panels, furniture, architectural | | 60″ × 96″ | 1524 × 2440 mm | Wide-format applications | | Custom cut | Variable | Specific dimensions on request |
The 48″ × 96″ sheet is the Canadian commercial standard — it fits most CNC and laser cutting beds, ships efficiently on standard pallets, and is available in the widest range of thicknesses and colors. When in doubt, this is the format to order.
Thickness Options: The Complete Range
Acrylic sheet is available in a wide thickness range, though not every thickness is stocked by every supplier. In Canada, the most commonly stocked thicknesses are 3, 4, 5, 6, 8, 10, 12, 15, and 19 mm. Specialty thicknesses (2 mm, 25 mm, and above) are available but may require longer lead times.
How Thickness Affects Properties
Rigidity and stiffness scale significantly with thickness. The relationship is roughly cubic — doubling the thickness gives roughly 8× the rigidity. This means that stepping from 6 mm to 8 mm gives you significantly more stiffness for panel applications, not just marginally more.
Weight is linear with thickness — a 6 mm sheet weighs exactly twice as much per square foot as a 3 mm sheet. For large installations, this matters both for structural support requirements and shipping costs.
Cutting difficulty also increases with thickness. Most hobby laser cutters (40–60W) handle 3–6 mm well; 8–10 mm requires higher power or multiple passes; above 10 mm is generally not practical for CO2 lasers under 80W. For table saw cutting, thickness above 10 mm requires slower feed rates and sharp blades to avoid chipping.
Thickness Selection by Application
The 6 mm thickness accounts for nearly a third of Canadian commercial acrylic orders — it's the sweet spot for signage, barriers, and display applications.
| Application | Minimum | Recommended | Notes | |---|---|---|---| | Picture frames, decorative accents | 2 mm | 3 mm | Lightweight, easy to cut | | Small display cases, POS risers | 3 mm | 4 mm | Clear boxes, product display | | Menu boards, indoor signs | 4 mm | 6 mm | Needs rigidity for wall mounting | | Countertop sneeze guards | 4 mm | 6 mm | Standard commercial specification | | Office partitions (freestanding) | 6 mm | 8 mm | Weight and rigidity for stability | | Furniture tabletops | 8 mm | 10–12 mm | Span and load dependent | | Shelving (up to 600 mm span) | 6 mm | 8 mm | Longer spans need more thickness | | Skylights and overhead panels | 10 mm | 12–16 mm | Engineering sign-off recommended | | Heavy outdoor structural panels | 12 mm | 16–25 mm | Load and span calculations required |
Color and Transparency Options
Acrylic sheet is available in far more than just clear. Canadian commercial suppliers typically stock or can order:
Clear: The default. Maximum light transmission (92%), glass-like appearance. Available in cast and extruded, all thicknesses.
Opal/Diffused White: Transmits light evenly without hot spots — the standard choice for backlit signage. P95 and similar diffuser grades are specified by most sign shops. Available in multiple diffusion levels (light, medium, dense) for different LED applications.
Colored: A wide range of transparent and opaque colors — from tinted transparent sheets (which let light through while adding color) to solid opaque colors for non-illuminated signage and furniture applications. Black and white opaque are the highest-volume colors after clear.
Frosted/Satin: Provides privacy while transmitting diffused light. Used for shower enclosures, office privacy panels, and decorative screens.
Mirror Acrylic: A reflective acrylic sheet used for decorative mirrors, ceiling installations, and branded display elements. Much lighter than glass mirror and shatterproof.
UV-Stabilized Grades: Available in clear and some tint options. Essential for any outdoor application. Evonik PLEXIGLAS® GS XT is a common specification for outdoor cast acrylic.
Acrylic Sheet Usage Growth in Canada
Volume growth has been consistent since the post-pandemic normalization, driven by commercial construction recovery, expanded signage demand, and the growth of digital fabrication services.
Cutting and Fabrication Options in Canada
Understanding your fabrication method should influence your thickness and sheet format choice.
Score-and-snap: Works on sheets up to 4 mm (3 mm is more reliable). Score deeply with a sharp carbide scribe against a metal straight edge, then snap cleanly. Fast and toolless — but only for straight cuts on thin sheets.
Table saw / circular saw: Works on all thicknesses. Use a fine-tooth carbide blade (60–80 teeth for 10″ blade) with the sheet masked to prevent surface scratching. Feed slowly on thick sheets. This is the standard production method for straight cuts.
Jigsaw / bandsaw: Best for curves and irregular shapes. Use a fine-tooth blade, keep speed moderate to avoid heat buildup and melting.
Laser cutting: Ideal for intricate shapes, lettering, engravings, and precision work. Works best on cast acrylic up to 10 mm. Produces flame-polished edges on clear cast material.
CNC router: Used for complex shapes, edge profiling, and high-volume production. Requires acrylic-specific tooling (single-flute O-flute bits) and proper speeds to avoid gumming.
Professional cutting service: For projects requiring precise dimensions without in-house fabrication equipment, many suppliers including FIDAR System offer cut-to-size services.
Installation Considerations
Thermal expansion: Acrylic expands approximately 0.07 mm/m/°C. Across a Canadian seasonal range of 60°C (summer to winter), a 2-metre sheet moves nearly 9 mm. Mounting systems must accommodate this — use oversized mounting holes (5 mm larger than the fastener) and non-rigid fasteners.
Support spacing: Acrylic sheet sags under its own weight if unsupported across large spans. For horizontal applications, support every 600–900 mm depending on thickness. Vertical panels are less critical but large unsupported sheets can bow in heat.
Cleaning: Use mild dish soap and warm water with a clean microfiber cloth. Avoid paper towels (scratch the surface), ammonia-based cleaners like Windex (cause crazing), and solvent cleaners that aren't specifically rated for acrylic.
Edge treatment: Sawn edges on acrylic can be left as-is for most applications, but for customer-facing applications, lightly sanding the edge (220 grit, then 400, then 800) and optionally flame-polishing it gives a professional finish.

Frequently Asked Questions
What is the most commonly used acrylic sheet size in Canada? The 48″ × 96″ (4′ × 8′) format is the Canadian commercial standard. It's compatible with most cutting equipment, ships efficiently, and is available in the broadest range of thicknesses.
What thickness of acrylic should I use for outdoor projects? A minimum of 6 mm for most outdoor applications, with UV-stabilized cast acrylic (not standard extruded). For structural outdoor applications (skylights, roof panels), 10–16 mm with engineering sign-off.
Can acrylic sheets be cut at home? Thin sheets (up to 4 mm) can be scored and snapped. Thicker sheets require a table saw, jigsaw, or router. Laser cutting is the best option for precision work. Professional cutting is recommended for anything requiring exact tolerances.
Where can I buy acrylic sheets in Canada? FidarSystem.com offers a comprehensive range of acrylic sheet formats and thicknesses with Canada-wide delivery from our Toronto warehouse.
Are acrylic sheets shatterproof? Acrylic is shatter-resistant, not unbreakable. It's 5–17× more impact-resistant than glass, but can crack under significant force. For applications requiring true impact resistance, polycarbonate is the appropriate material.
How do I clean acrylic sheets without scratching them? Use mild soap, warm water, and a soft microfiber cloth. Never use ammonia-based cleaners (Windex, etc.), rough cloths, or paper towels. For stubborn marks, a dedicated acrylic cleaner/polish works well.
