How to Measure Vacuum Seal Bags and Vacuum Pouches
Choosing the right vacuum bag size is critical for a proper seal. Too small and your food won't fit; too large and you waste material. This guide explains exactly how to measure vacuum seal bags for food storage, sous vide cooking, and commercial packaging.
How Vacuum Bag Dimensions Are Measured
Vacuum bags are measured width × length in inches (the flat, unfolded size). For example, a 10" × 13" vacuum bag means:
- Width: 10 inches (side to side when laid flat)
- Length: 13 inches (top to bottom)
Important: Measurements refer to the internal bag dimensions (the usable space inside). Always add 2-3 inches to your product length to allow room for sealing.
Step-by-Step: Measuring Your Product
1. Measure the Item Width
Lay your product flat (or at its widest point). Measure side-to-side. Add 1 inch for clearance and sealing space.
2. Measure the Item Length
Measure from top to bottom. Add 3 inches minimum to allow for:
- 2 inches at the top for sealing
- 1 inch at the bottom for clearance
For reusable bags (cut and reseal), add 4-5 inches so you can trim and reseal multiple times.
3. Consider Product Thickness
Vacuum bags are flat (2D), but your product is 3D. If your item is thick (steaks, bulky vegetables), the bag needs extra width to wrap around. Add half the product thickness to your width measurement.
Common Vacuum Bag Sizes by Use Case
| Product Type |
Recommended Size |
| Individual steaks, chicken breasts | 6" × 10" or 8" × 12" |
| Family-size portions (4-6 servings) | 10" × 13" or 11" × 16" |
| Whole roasts, brisket, large cuts | 12" × 18" or 14" × 20" |
| Sous vide vegetables, sides | 6" × 10" or 8" × 12" |
| Bulk dry goods (coffee, flour) | 10" × 16" or 12" × 18" |
| Liquids, soups, sauces (freeze flat) | 8" × 12" or 10" × 13" |
Vacuum Pouch Volume Guide
Not sure how much a bag holds? Use this capacity reference:
- 6" × 10": 1-2 cups (~8-16 oz)
- 8" × 12": 3-4 cups (1 quart)
- 10" × 13": 6-8 cups (1.5-2 quarts)
- 11" × 16": 10-12 cups (2.5-3 quarts)
- 12" × 18": 1 gallon+
Tips for Perfect Vacuum Sealing
- Leave 2-3 inches of empty space at the top for a strong seal
- For liquids: Freeze flat first, then vacuum seal (prevents liquid from being sucked into the machine)
- For sharp items: Wrap in paper towel to prevent punctures
- Label before sealing: Write contents and date on the bag with a permanent marker
What Mil Thickness Do I Need?
Vacuum bag thickness (mil) affects durability and puncture resistance:
- 3 mil: Standard for home food storage, sous vide, light commercial use
- 4 mil: Heavy-duty for bones, frozen goods, long-term freezer storage
- 5-6 mil: Industrial-grade for commercial kitchens, sharp or abrasive items

Frequently Asked Questions About Vacuum Bag Sizing
What size vacuum bag do I need for chicken breasts?For individual chicken breasts, use a 6" x 10" or 8" x 12" vacuum bag. For family packs of 4 to 6 breasts, use a 10" x 13" or 11" x 16" bag. Always add 2 to 3 inches to your product length so there is room for the seal. How do I measure for bulk vacuum sealing?Measure your product at its widest point, then add 1 inch to the width for clearance and at least 3 inches to the length (2 inches for the seal plus 1 inch of clearance). For thick items, add half the product thickness to the width. If you plan to cut and reseal the bag for reuse, add 4 to 5 inches to the length instead. What mil thickness is best for freezer storage?3 mil is the standard thickness for home use, sous vide, and short-term freezer storage of 3 to 6 months. Step up to 4 mil for bone-in cuts, long-term freezing of a year or more, and commercial kitchens, and to 5 or 6 mil for sharp or abrasive items and storage beyond two years. Can I use the same vacuum bags for sous vide and freezer storage?Yes. BPA-free, FDA-compliant vacuum bags work for both sous vide cooking and freezer storage as long as they are rated from -40°F to 212°F, certified food-safe for direct food contact, and at least 3 mil thick so they resist punctures during cooking. All of our vacuum pouches meet these standards. How much does a 10" x 13" vacuum bag hold?A 10" x 13" vacuum pouch holds approximately 6 to 8 cups, or 1.5 to 2 quarts. That is enough for family-size portions of 4 to 6 servings, a medium roast or several steaks, 1.5 to 2 lbs of ground meat, or 2 to 3 lbs of coffee beans. Why are vacuum bags measured flat instead of by volume?Vacuum bags are measured width x length as flat dimensions because the volume changes once the air is removed during sealing. Flat measurements stay consistent across every product and make it easy to match a bag to the width of your vacuum sealer. What happens if my vacuum bag is too small?If the bag is too small the food will not fit or will be compressed too tightly, there is no room left at the top for a proper seal, and overcrowding can puncture the film. When in doubt, go one size up: extra space does not hurt, but too little space ruins the seal. Can I cut vacuum bags to custom sizes?Yes, if you use vacuum bag rolls. Cut the roll to your desired length plus 3 to 4 inches for sealing, seal one end with your vacuum sealer, then insert the food and vacuum seal the open end. Rolls let you make custom lengths for odd-shaped items and reduce waste because you only use what you need. Wholesale Vacuum Bag Pricing
