Compare the tote's width, height, depth, opening and strap drop with the items you plan to carry and the layers you will wear. Check interior measurements and the opening rather than relying on a screen-size label or a bag's outside dimensions alone. Fit claims and strap-drop ranges apply to the exact model and maker.
Tote size names do not tell you whether your belongings will fit. Compare the inside, opening and handle measurements with your actual items and how you plan to carry the bag.
Compare the measurements
| Measurement | How to use it |
|---|---|
| Width, height and depth | Compare the outside dimensions and usable interior with an item you own. Check whether the maker defines width front-to-back or across the front. |
| Opening | Compare the top opening with the largest item you plan to insert, and check the closure. |
| Strap drop | Compare the handle or strap distance with your preferred carry and the clothing layers you expect to wear. |
Check a model’s dimensions and fit claims
The Sak measures length across the base, width from front to back, and height from the bottom to the top of the bag body. It notes that a wider top opening can be listed separately and measures strap drop from the top of the handle to the top of the bag. Its guide describes 9 to 12 inches as shoulder-drop examples and 22 inches or more as crossbody examples for its range, not universal cutoffs. Marc Jacobs lists dimensions and fit examples by tote size, such as the large tote’s 9-inch handle drop and stated fit for a 15-inch laptop; those details apply to that model and listing.
Before buying, measure the device or item including its case, then compare it with the tote’s usable interior and opening. Pocket placement, lining and a closure can change what fits even when the outside dimensions look sufficient.
Check carrying comfort and material
Compare strap drop while wearing the layers you expect to use, and check whether the straps sit comfortably with the planned load. Review the maker’s care instructions for the exact exterior and lining. Our handbag materials guide explains composition and care, while the backpack fit guide covers torso and harness measurements.

Common questions
How do I choose a tote bag size?
Compare the bag's interior dimensions and opening with the largest items you plan to carry, including any cases or sleeves. Check the exact model's product details rather than relying on a general size name.
What is strap drop on a tote?
The Sak measures strap drop from the top of the handle or strap to the top of the bag. Check the maker's definition and compare the listed drop with how you plan to carry the exact bag.
Will a tote listed for a 15-inch laptop fit every 15-inch laptop?
Not necessarily. Laptop bodies and cases differ, and a bag's opening and interior measurements matter. Treat a maker's fit claim as specific to the named tote and compare your device's dimensions.
Should I compare the tote opening or outside width?
Compare both. A wide body can still have a narrower opening, while lining, pockets and structure reduce usable interior space.
