When selecting the right size for your product, many customers often ask how to correctly measure the size of a bag. Whether it’s a reclosable zip bag or a drawstring bag, choosing the correct size is crucial. Below, we will explain in detail how to choose the size for each type of bag and how to measure it.
Choose the Right Size Drawstring Bag: Determine the Width and Height of the Item
- Width: Measure the widest part of the item, then add the thickness of the item. For example, if you are placing a pair of shoes in the bag, and the shoes are 12 inches wide and 3 inches thick, the bag’s width should be at least 12 inches (width) + 3 inches (thickness) = 15 inches. This ensures that the item will fit comfortably in the bag, without being too tight or affecting the bag’s closure.
- Height: Measure the maximum height of the item from top to bottom. For thicker items, the height of the bag should be slightly larger than the actual height of the item to ensure that the bag can close properly and prevent the item from being squeezed. For example, if the item’s height is 10 inches and the thickness is 2 inches, the bag’s height should be at least 10 inches (height) + 2 inches (thickness) = 12 inches.
Note: These measurements only refer to the width and height of the item. To ensure that the item fits easily into the bag, it’s important to add appropriate extra space to the bag’s dimensions.
Choose the Right Size Drawstring Bag: Add Appropriate Allowance
After determining the width and height of the item, adding 1/2 inch to 2 inches of allowance is very important to ensure the bag can hold the item and be easy to use.
- Small items (such as keys, phones, etc.): Add 1/2 inch of allowance.
- Medium items (such as sports shoes, towels, books, etc.): Add 1 inch of allowance.
- Large items (such as coats, sports equipment, etc.): Add 2 inches of allowance.
These allowances ensure that the bag not only holds the item but also allows the drawstring or closure to work smoothly, preventing the bag from being too tight and difficult to use.
Summary
By following these two steps, you can accurately choose the right size for a drawstring bag:
- Measure the width and height: Determine the bag’s base dimensions by adding the thickness to the item’s width and height.
- Add appropriate allowance: To ensure the bag can hold the item comfortably and is easy to use, add 1/2 inch to 2 inches of allowance.
This way, you can select a drawstring bag that fits your item and is convenient to use.

FAQs
Q1: How do I measure the size of a reclosable zip bag?
Answer: For reclosable zip bags, measure from the bottom of the bag to the zipper part, excluding the lip above the opening. This will give you the actual storage space of the bag.
Q2: Does the height of the bag include the drawstring part?
Answer: For most bags, the height does not include the drawstring part. Only measure from the bottom of the bag to the top opening, which is the maximum height of the bag.
Q3: How should I measure the width of a drawstring bag?
Answer: The width of a drawstring bag should include the widest part of the item plus the thickness of the item. For example, if the width of the item is 12 inches and the thickness is 3 inches, the bag’s width should be 15 inches.
Q4: How is the measurement of a reclosable zip bag different from a slider bag?
Answer: For reclosable zip bags and slider bags, measure from the bottom of the bag to the zipper part, excluding the lip above the opening. This ensures that you are measuring the actual storage space of the bag.
Q5: How do the dimensions of a drawstring bag fit different types of items?
Answer: When selecting a drawstring bag, make sure to measure the width, thickness, and height of the item, and add the appropriate allowance based on the shape and size of the item. Larger or thicker items will need a larger bag, and you should add 1 to 2 inches for allowance.
Q6: How do I handle stacked items when choosing a bag size?
Answer: When placing multiple items in a bag, first measure the total thickness of the stacked items, then add it to the width of the bag. For example, when adding multiple towels, ensure the bag width accommodates the total thickness of the stacked towels.
Q7: Why does the material of the bag affect the size choice?
Answer: The material of the bag determines its stretchability and load-bearing capacity. For example, thicker materials (such as canvas or Velour) may require a larger size because these materials usually do not have much elasticity and can cause a tight fit. Therefore, thicker material bags require more allowance to ensure the items can be comfortably placed and removed.
