How to Choose a Bag Size and What to Ask Before Ordering
Choose a bag size by what you carry, how you wear it and your build, then confirm measurements before ordering.
MMBAG 88 · Published · Updated
Quick answer: To choose a bag size, start with what you carry every day, decide how you will wear the bag, and then compare width, height, depth and strap drop with items you already own. Before ordering, confirm the exact measurements of the version you are considering, the strap length and what fits inside, so the size matches how you will actually use it.
Size is one of the most common reasons a bag ends up unused. A style can look perfect in a photo and still be too small for your phone or too large for your frame. This guide gives you a simple method for choosing a size and a short list of questions to ask on WhatsApp before you decide.
Step 1: List What You Carry
Empty your current bag and write down what you carry most days. Typical items:
Phone
Wallet or card holder
Keys
Sunglasses
Small cosmetics pouch
Earphones or charger
Tablet, notebook or water bottle
This list is your baseline. A bag that fits only half of it will frustrate you, and a bag far larger than it will feel empty and shapeless.
Measure the largest items
Your phone and wallet usually set the minimum size. Measure their length and width, and note whether you want them to lie flat or stand upright.
Step 2: Decide How You Will Wear It
The way you carry a bag changes what size feels right.
Top handle
Carried in the hand or the crook of the arm. Medium and smaller sizes feel easier to carry for long periods.
Shoulder
Worn under the arm or on the shoulder. Check the strap drop, the distance from the top of the strap to the top of the bag, so it fits under your arm comfortably.
Crossbody
Worn across the body. Smaller sizes sit neatly at the hip. Check the strap length and whether it is adjustable.
Tote
Carried on the shoulder with large capacity. Make sure the handles are long enough to fit over a coat.
Step 3: Understand the Measurements
Bag measurements are usually given as width × height × depth.
Width is measured across the base or the widest part.
Height is measured from the base to the top edge, not including handles.
Depth is measured from front to back at the base.
Strap drop is the height of the handle or strap above the bag.
Depth is the most overlooked number. Two bags with the same width and height can hold very different amounts if one is much deeper.
Compare with a bag you own
The easiest way to picture a size is to measure a bag you already use and like. Compare it number by number with the style you are considering.
Step 4: Consider Proportion
Bag size also changes how a bag looks on you.
Very small bags can look smaller still on a taller frame.
Very large bags can look oversized on a petite frame.
Medium sizes are usually the most versatile across builds and outfits.
There is no strict rule. If you are unsure, ask for a photo of the bag held or worn, which shows scale better than a flat shot.
Common Size Labels
Many styles use labels such as mini, small, medium and large. These labels are not standard across styles. A "medium" in one design may be close to a "small" in another. Always check the measurements rather than relying on the label.
What to Ask Before Ordering
Once you have a size in mind, confirm these points on WhatsApp for the exact version you are considering:
What are the exact width, height and depth?
What is the strap drop, and is the strap adjustable or removable?
Does it fit my phone and wallet? Share their measurements.
Is the bag structured or soft? Soft bags can fit more but lose shape when full.
How does it close? A flap, zip or open top affects usable space.
Can I see it held or worn? A photo with a hand or on a shoulder shows real scale.
You can also ask about the leather, hardware and lining at the same time. Our leather guide explains how materials affect structure, and our order photo guide explains what to check in the photos you receive.
Where to See Sizes in Practice
Order photo records on /shipping show many styles from several angles, which helps you judge proportion. Material photos on /factory show leather thickness and texture, and customer feedback on /comments can mention fit and capacity. When you are ready, send the item code or a reference photo with your preferred size through the contact page.

FAQ
What bag size is best for everyday use?
A medium size that fits your phone, wallet, keys and one or two extras is the most versatile choice for daily use. Check the depth as well as the width.
How do I know if my phone will fit?
Measure your phone and compare it with the interior width and height of the bag. Ask for confirmation for the exact version before ordering.
Are mini and small sizes the same across styles?
Size labels vary between styles, so compare the actual measurements.
What is strap drop and why does it matter?
Strap drop is the height of the strap or handle above the bag. It decides whether a bag sits comfortably on the shoulder or only works carried in the hand.
Can I ask for a size that is not listed?
The site shows only part of the catalog. Send a reference photo on WhatsApp and ask which sizes are available for that style.
