Garbage Bag Sizes: How to Choose the Right Bin Liner for Your Needs
Share
Using the wrong size garbage bag can lead to leaks, spills, and wasted time. The right fit? It makes waste management clean, fast, and frustration-free.
At Matthews Cleaning Company, we supply a full range of commercial bin liners to suit everything from kitchen caddies to 240 L wheelie bins. In this guide, we’ll help you match garbage bag sizes to your bin type so your staff, site or household stays clean and compliant.
Why Garbage Bag Size Matters
Too small, and the liner slips down or tears. Too big, and you waste material and risk messy overhangs. Choosing the correct bin liner size:
- Improves hygiene and odour control
- Speeds up changeovers
- Reduces plastic waste and costs
- Prevents leakage and overfilling
Quick Reference: Garbage Bag Size Chart
| Bin Size | Recommended Bag Size | Product Example |
|---|---|---|
| 10–15 L (Bathroom / Caddy) | 450 × 520 mm | Use 18 µm liners or compostable options |
| 36 L (Under-sink / Office Bin) | 500 × 600 mm | Classic 36 L Black Bin Liners |
| 54 L (Kitchen / Café Bin) | 600 × 740 mm | Classic 54 L Bin Liners |

How to Measure for Bin Liners
To find the perfect garbage bag size, use this formula:
- Width: Half of the bin’s perimeter (Width × 2) + 100 mm for overhang
- Length: Height of the bin + half the diameter of the bin base
Or, skip the maths—just measure the bin and match it to our product chart above or contact our team for quick help.
Choosing the Right Thickness (Microns)
Garbage bag thickness affects puncture resistance:
- 18–20 µm: Ideal for light office waste, tissues, paper
- 25–30 µm: Suitable for kitchen, café and food scraps
- 30+ µm: Required for sharp, heavy, or industrial waste
All our Classic and Enviroplus bin liners are tested for commercial-grade durability, so you can bag waste with confidence.
