How to Measure a Plastic Bag in Singapore with Plastic bag size chart singapore

Plastic bag dimensions are always listed as Width × Length × Gusset (W × L × G), measured in millimetres or inches. Here is what each measurement means:

• Width — the opening of the bag, measured flat across the top
• Length — the distance from the top opening to the bottom seal
• Gusset — the side fold that allows the bag to expand. A bag with no gusset is called a “flat bag.”

For T-shirt bags, the length includes the handle area. For ziplock bags, measure the usable space below the seal track, not the total film length. Getting these plastic bag dimensions Singapore right is critical — even a 20 mm error can mean your product does not fit or the bag looks sloppy.

Standard Plastic Bag Size Chart by Type

Here are the most common standard sizes available from Singapore suppliers:

What Is a Gusset and Why Does It Matter?

A gusset is a folded side panel that lets the bag open wider to hold bulkier items. When a bag size is listed as 300 × 400 × 120, the 120 mm gusset means the bag can expand up to 240 mm wide (gusset × 2) when filled. For retail shops in Singapore, gusseted bags are ideal for boxed products or irregularly shaped items. Flat bags work best for flat or thin products like documents, greeting cards, or garments on hangers.

Sizing Tips for Common Products

• Baked goods: Add 40–60 mm to the product width and length so the bag is not skin-tight — this looks better and avoids tears at the seams.
• Food containers: Measure the container diagonal, not just the width, since round containers need more bag width than square ones.
• Apparel: A 250 × 350 mm die cut bag fits most folded T-shirts; use 300 × 400 mm for thicker items like hoodies.
• E-commerce: Choose courier bags 30–50 mm larger than your largest product dimension to allow padding and easy insertion.

Custom Bag Sizes — When to Order Them

Standard sizes cover most needs, but some products demand custom bag sizes. If your item is unusually shaped, very heavy, or needs a branded fit, a custom size eliminates excess material and looks more professional. The trade-off is a higher MOQ — typically 5,000–10,000 units for custom sizes vs 1,000–3,000 for standard. For grocery stores in Singapore with standard product ranges, sticking to standard sizes is almost always more cost-effective.

When ordering custom sizes, provide your supplier with the exact product dimensions plus your desired clearance. Also consider the bag thickness — thicker bags need slightly more room to fold and seal cleanly.

Bag Size Selection Tips for Singapore Businesses

Choosing the right bag size saves money and improves customer experience. For retail stores, a medium bag (18×8×24″) covers most purchases. For grocery items, a larger bag (24×12×30″) handles bulky products. Consider two sizes — small for 1–3 items and large for full baskets. Custom sizes are cost-effective at 10,000+ bags and improve your brand checkout presentation.

Work with your supplier to determine optimal bag dimensions for your specific products. Well-proportioned bags use less material, reduce overall packaging costs, and create a better customer experience at the checkout counter in Singapore retail stores. For best results, request a size consultation from your packaging supplier who can recommend optimal dimensions based on your product range and store layout.
