When you want to buy or customize a tote bag, you will have many questions. What size is right for your needs? How much capacity do you need for your products? Will a canvas tote bag meet your specific needs? 

Now we have good news for you. This guide will give you a detailed guide and basic tips on how to measure tote bags. 

Why Is It Important To Get The Tote Bag Size Right? 

Tote bags have become a must-have accessory for personal and professional occasions. They come with features to suit every need.

For businesses, these versatile and practical bags are not only tools for everyday use but also powerful branding opportunities and thoughtful gifts for special occasions. Here are reasons to choose the right tote bag size:

• Functionality: If a client needs to carry a laptop, recommending a small tote bag can lead to dissatisfaction. Accurate sizing ensures practicality.
• Professional Branding: Correct dimensions prevent logo distortion during printing, ensuring a polished and professional look.
• Informed Decisions: Providing clear dimensional information helps customers choose the right bags for their specific needs, improving satisfaction and brand loyalty.

Consider How and Why You’ll Use Your Tote 

Before settling on a tote bag size, it’s essential to define its primary purpose. Are you heading to the beach, carrying groceries, toting gym clothes, or looking for a bag that doubles as a laptop carrier? Perhaps you need a sleek option for trade shows, events, or even as a unique promotional giveaway at your next conference. Identifying your main use case will make it much easier to pinpoint the ideal size and features.

Think through the typical items you’ll carry: books, a yoga mat, a water bottle, a lunch box, or maybe even a wrapped gift. Jotting down these essentials gives you a tangible reference when evaluating tote dimensions.

Don’t Forget All the Measurements

It’s a common mistake to only look at width and height, but don’t overlook depth (the gusset) and handle or strap length. These measurements play a crucial role in both the tote’s capacity and how comfortable it is to carry. For example:

• Depth matters: A wider gusset means more space for bulky items, perfect for shopping trips or gym visits.
• Handle or strap length: Impacts how you carry the tote—over your shoulder, in your hand, or across your body. The right strap length prevents awkward carrying and ensures comfort, especially when the bag is loaded with heavier items.

Picture this: trying to squeeze a large water bottle into a shallow tote, or slinging a bag with a too-short handle over your shoulder—neither is practical or comfortable. Just as important, choosing the correct measurements prevents the all-too-common scenario of a tote that can’t quite fit your laptop or leaves important items sticking out.

By taking the time to consider all these factors, you’ll ensure your tote bag is not just stylish but truly functional for your unique needs.

What Are The 4 Measurements Of A Bag?

To measure a tote bag size, focus on these dimensions:

• Height: The vertical length from the bottom to the top edge (excluding the handles).
• Width (Length): The horizontal span across the front of the bag.
• Depth (Gusset): The extra space at the sides or bottom that adds capacity.
• Handle/Strap Length: The full length of the strap from end to end.

How Depth and Handle Length Affect Usability

When evaluating a tote bag’s functionality and comfort, it’s important to consider more than just the width and height. The depth (or gusset) and the handle or strap length are key components that can make or break your daily experience with the bag.

• Depth (Gusset): This measurement determines how much the bag can actually hold. A roomy depth means your tote can handle bulkier items—think gym shoes, a stack of books, or even a lunchbox. Too little depth, and suddenly you’re fighting a losing battle to fit your essentials.

• Handle/Strap Length: The right handle length guarantees comfort and versatility. A longer strap lets you sling the bag over your shoulder or wear it crossbody, which is useful for commuting or shopping. Handles that are too short or too long, however, can cause awkward carrying angles or force you to hold the bag in your hand when you’d rather go hands-free.

Choosing the right depth and strap length ensures your tote bag isn’t just a storage space—it’s a comfortable, reliable tool you’ll want to reach for every day.

The Tools You Need 

You first need to prepare some tools for the measurement. Here we will give you a list：

• Measuring Tape or ruler: A flexible tape works best as it can easily measure around curves.
• Scale: This is typically for gram weight measurement.
• Flat Surface: Lay the bag flat on a stable surface to get an accurate measurement.
• Pen and Paper (or Device): Record your measurements as you go.

How To Measure A Tote Bag

To know how to measure a tote bag, you need to know the width and height of the bag first. You can measure it directly from the front of the bag using a ruler or tape measure.

When measuring the height, you need to put the measuring tool in the middle of the bag.

Measure the height from the bottom of the tote to the highest point of the bag. Please note that the height of the bag doesn’t include the handle part.

Measuring the width is to measure the widest part of the handbag from one side to the other. 

Measure the depth from the front to the back of the widest part of the handbag. Of course, not every bag has this design. For the flat tote bag, you just need to measure the height and width. Okay, next, I will introduce how to measure tote bags with gussets.

How To Measure The Tote Bag With Gusset 

Of course, when it comes to custom tote bags, you’ll find a lot of tote bags with gussets. So do you know what a gusset is? What does it do? A gusset is to increase the capacity of a bag by creating extra space for loading goods.

You may also know that gusseted tote bags have some extra fabric, and measuring this type of tote bag becomes a little bit complicated.

To measure the full gusset reusable bag, you just need to stand it upright on a tabletop with the front of the bag facing you.

1. Width: Measure from left to right
2. Depth: Measure from front to back
3. Height: Measure from the bottom to the top edge.

To measure the bottom gusset tote bag, you just need to lay the bag flat on the table and put the bottom of the bag in front of you.

1. Width: Measure from left to right
2. Height: Measure from top to bottom of the bag
3. Bottom Depth: Measure from top to bottom of the bag.

Understanding Types of Gussets

While measuring, it helps to know that there are several types of gussets you might encounter in tote bag designs:

• Box Gusset: This is the most straightforward type, with an additional rectangular area at the base and sides, giving the bag a boxy shape. When measuring, simply use the steps above—width, height, and depth—keeping in mind that the gusset adds extra space at the base and sides.

• U-Type (Two-Seam) Gusset: These gussets wrap around the sides and bottom, creating a “U” shape when viewed from the side. Picture the bag filled with items as you measure, since the gusset expands the bag’s volume significantly. Use the same width, height, and depth method, but consider the added space from the seams.

• T-Type (Single Seam) Gusset: This type features an extra panel only at the bottom, forming a “T” shape when the bag is laid flat. The depth measurement applies just to the base, not the upper part of the tote. So, when measuring a T-type gusset bag, focus on the base to get an accurate depth.

By recognizing the gusset style, you’ll be able to measure your tote bag accurately, ensuring you get the right dimensions for capacity and custom printing. This attention to detail makes all the difference, especially when ordering or designing bags for promotional or practical use.

How To Measure Tote Bags For Printing

Reusable tote bags are a great marketing promotion. When you print the custom tote bags, you need to print the logo you need on the bag. Except for determining the size of the logo, you need to determine a printable size.

• Determine the printable area: Find a flat, unobstructed panel where the design will be located.
• Measure the panel: Measure only the usable area, not the seams or folds. For example, a 16-inch wide x 18-inch high tote may have a printable area of 14 inches wide x 16 inches high.
• Consider print margins: leave a 1″ inch margin around the edges for bleed (if needed).

Recommended Imprint Sizes

About how big should a design be on a tote bag? Here’s a quick reference table for recommended imprint sizes:

How To Measure The Length Of A Tote Bag Handle/Strap

Strap length refers to the full length of the shoulder strap from one end to the other. Measure from the top edge of the tote bag to the highest point where the handles meet. 2 x this length is the length of the handle.

This measurement is related to whether the canvas tote is suitable for crossbody or shoulder to carry, which will improve your customer’s experience when they buy it.

How To Measure the Drop Length

The drop length is the distance from the top of the shoulder strap to the top of the bag’s body. It is an important factor to judge how comfortable it is to use a handbag or shoulder bag.

To determine the drop length, you first hang the handbag on and use a ruler to measure from the top position of the shoulder strap to the highest point of the bag opening.

What Are The Most Popular Tote Bag Sizes?

The most common tote bag sizes include small (10” x 12”), medium (15” x 16”), and large (18” x 20”). Each size serves different purposes, from cosmetics to groceries. The tote bag is a versatile accessory, so there are absolutely no fixed standard tote bag dimensions. It can be customized and is available in a wide range of tote bag design sizes!

When wondering what size is “best,” it really depends on your intended use. For instance, if you’re searching for a compact option for daily essentials, small bags often have dimensions around 13″ W x 15″ H or close to 15″ x 12″ x 4″. Retail shops may offer these as branded gift bags for product packaging or small takeaways.

But then again, there will be the best-selling and most popular tote bag types on the market, 13″ W x 15″ H. Retail shops may offer small totes as branded gift bags for product packaging.

Well, most people want to know what the average size of a tote bag is. Then, that brings us to the medium size. The most common size is 15″ W x 16″ H x 5″. These totes are perfect for grocery bags, books, laptops, etc. For personalized events like promotions, this is a perfect size and it won’t be an extra burden. It’s a great answer when you want to know about a standard-size tote bag.

For example, a boutique in New York ordered medium tote bags (15” x 16”) to package their handmade soaps, offering both functionality and branding.

Medium-sized bags typically measure up to 15″ W x 16″ H  x 5″ D, making them the go-to for everyday errands, work, or promotional events. This size is especially popular because it strikes a balance between portability and capacity.
Of course, you can also choose a larger size if you have larger needs. Most of the large tote bags measure approximately 20″ W x 17″ H x 6″ D, though you’ll also find common large bag dimensions like 15″ W x 19″ H x 5″D. Perfect for bulk shopping, traveling, or heavy-duty use, these bags accommodate everything from beach towels to farmers market hauls.

Tote bags come in various sizes, but these are the most common:

• Small: 13″ W x 15″ H or 15″ x 12″ x4″
• Medium: 15″ W x 16″ H x 5″ D or up to 15″ W x 16″ H x 5″ D.
• Large: 20″ W x 17″ H x 6″ D. 

Did You Know? Medium-sized totes are the most popular choice for promotional campaigns due to their practicality and branding space.

Most Common Handle/Strap Length Of Tote Bags

Tote bags come with various handle lengths, but do you know how long the handles should be on a tote bag? An ideal length for tote bag handles is around 21 to 26 inches. Of course, this will vary depending on your tote bag size.

The short handles typically about 14″-18″ with a drop of 6″-8″, are perfect when you need a handbag for quick errands or as a fashion accessory. 

The standard and most common easy-to-use straps are medium-length handles, about 20″-22″ in length, and a 9″-1″ drop. The medium-length handles are a good balance between comfort and functionality, especially for medium-sized handbags.

If you need to carry it over your shoulder or crossbody, then the long straps are designed for that, and the length is about 26″-30″. The longer handles provide more carrying comfort, especially for heavier or larger items, allowing the bag to rest comfortably on the shoulder.

How To Measure Bag Weight And Thickness

It is especially important to calculate the weight and thickness of canvas totes accurately for bulk customization and sourcing. These measurements will make sure your bags meet performance standards and your customers’ expectations.

Weight:

1. Use a Precision Scale: To weigh a bag, you should put it on a scale to get an exact figure in grams or ounces.
2. Record and Test: Write down the figure. If you need to, test the bag’s load capacity by adding items.

Thickness:

1. Use a Micrometer: Measure the bag’s material thickness at multiple points, especially at the base and sides.
2. Record Measurements: Write down the measurements in millimeters or linear inches for quality and durability checks.

Ok, now, we will give you an example of how to measure non-woven bags.
