Try our free Bin Bag Size Calculator

The calculator matches this information with the closest product in the Hygenol range and recommends an appropriate strength. Bin designs and capacity ratings vary between manufacturers, so the result should be used as a practical guide. If an exact fit is essential, compare the displayed bag dimensions with a liner that already fits or contact Hygenol for advice.

Choosing the right bin bag can prevent split sacks, leaking waste and liners that constantly fall inside the bin. The best option depends on three things: the capacity of the bin in litres, the type of bin being used and the weight and type of waste going into it.

What Size Bin Bag Do I Need?

The bin’s capacity in litres is normally the best place to start. This may be printed on the bin, shown on its packaging or included in the original product listing.

As a general guide:

• Up to 15 litres: Pedal bin, bathroom or desk bin liners
• 16–35 litres: Square, office or swing bin liners
  
• 36–90 litres: Standard refuse sacks
  
• 91–120 litres: Large commercial or trashcan liners
  
• 120–240 litres: Specialist wheelie bin liners

These ranges are a useful starting point rather than an exact rule. Bin shapes vary, and the bag must also cover the base and fold securely over the rim. This is why a 50-litre kitchen or swing bin may require a 90-litre refuse sack. The extra capacity does not necessarily mean the bag is excessively large once it is fitted inside the bin.

Why Capacity Is Better Than External Measurements

External bin measurements can be misleading because they may include lids and hinges, pedal mechanisms, handles, outer casings, tapered sides & wheels and wheel housings. The internal container can therefore be considerably smaller than the published width, depth and height suggest. Using the manufacturer’s stated litre capacity usually provides a more consistent way to select a bin liner. If the capacity is unknown, the dimensions of a bag that already fits can provide a useful comparison.

Light, Medium or Heavy Duty Bin Bags?

Bin bag size and strength are separate considerations. A bag can be large enough for the bin but too weak for its contents.

Light duty liners are suitable for:

• Paper and tissues
  
• Empty wrappers
  
• Lightweight packaging
  
• Dry office waste
  
• General desk-bin waste

Choosing light-duty liners for lightweight waste can be more economical than automatically purchasing a heavy-duty product.

Medium duty refuse sacks provide additional tear resistance for:

• Mixed workplace waste
  
• Moderately weighted packaging
  
• General kitchen waste
  
• Busier communal areas

They offer a practical balance between cost and strength for everyday commercial use.

Heavy duty sacks should be considered for:

• Wet waste
  
• Food waste
  
• Heavier mixed waste
  
• Bulky non-sharp items
  
• Demanding commercial environments

Hygenol also supplies extra-heavy and super-heavy refuse sacks for more demanding applications.

Black, Clear or Biodegradable Refuse Sacks?

The colour and material of the bag may also be important.

Black Refuse Sacks

• Black sacks conceal their contents and remain the standard choice for general workplace and commercial waste.

Clear Refuse Sacks

• Clear sacks allow the contents to remain visible. They may be useful where a business has particular security, inspection or waste-separation procedures.

Biodegradable Refuse Sacks

• Ideal for organisations reviewing the environmental impact of their consumables.

Correct waste separation and disposal arrangements remain important, regardless of the material used to manufacture the sack.

Common Bin Bag Mistakes

Avoiding these common mistakes can reduce waste, mess and unnecessary expense:

• Choosing by external measurements alone: These can include parts of the bin that the liner never touches.
  
• Buying the largest sack available: Excess material can interfere with lids and pedal mechanisms.
  
• Using heavy-duty sacks for light waste: This may increase costs without providing a practical benefit.
  
• Choosing by capacity but ignoring strength: Wet or heavy waste may split a lightweight liner.
  
• Overfilling the bag: Even a suitable sack can fail if it becomes too heavy to lift safely.
  
• Using wheelie-bin liners indoors: These are normally much larger than standard indoor refuse sacks.
  
• Using ordinary bags for sharp waste: Specialist waste requires an appropriate container or sack.

Frequently Asked Questions

Can I Use a 90-Litre Bag in a 50-Litre Bin?

Yes. A 90-litre refuse sack can be suitable for many 40 or 50-litre kitchen and swing bins. The additional material is used to cover the base and fold over the rim.

How Can I Find My Bin’s Capacity?

Check the underside of the bin, its packaging or the original online product listing. Capacities are normally shown in litres.

Are Heavy-Duty Bin Bags Always Better?

No. Heavy-duty sacks are useful for wet, bulky or heavy waste, but light-duty liners are normally sufficient for paper, tissues and lightweight office waste.

What If I Do Not Know the Bin Capacity?

Choose the closest bin type in the Hygenol calculator. It will use a typical capacity for that style of bin and provide the nearest stocked option.

Choose the Right Bin Bags for Your Business

The right bin bag should fit securely, contain the expected waste and be strong enough to remove safely.

Start with the bin capacity, choose the appropriate liner type and then select a duty suited to the contents.
