Shopping for a Louis Vuitton bag online can be a bit tricky because each model comes in several sizes. Also, Louis Vuitton’s sizes are acronyms and numbers, and it can be difficult to understand the difference between the sizes.

We’ve put together this guide to help you determine which size is the best choice for you. You’ll find the dimensions, carrying capacity, and photo references of 4 popular Louis Vuitton bags - the Cabas, Keepall, Neverfull, and Speedy.

With the help of this guide, you’ll be able to pick the right size bag and feel confident you made the best choice.


The Cabas bag comes in 3 sizes: Piano, Mezzo, and Alto



Width: 12 in.

Length: 4.9 in.

Height: 9.8 in.

The Piano is the smallest Cabas bag. Although it’s a “small” bag, its size is comparable to what most would consider a medium size handbag.

It’s roomy, but not oversized, and could easily carry the following items with a little room to spare for some smaller items:

  • Large wallet
  • Eyeglasses case
  • Small makeup bag with the basics (mascara, foundation, eyeliner, lipstick, small eyeshadow pallet)
  • Hand lotion



Width: 15 in.

Length: 6.1 in.

Height: 13 in.

Mezzo is the next size down from Alto. The biggest difference between the two is the width, with Mezzo’s being 5 inches shorter.

The Mezzo is a little more practical than the Alto as an everyday bag. It’s still a large bag, but it’s perfect for someone who likes to carry their entire life in their purse.

You can easily carry all of the following items in a Mezzo:

  • Medium sized makeup bag
  • Pair of flats
  • Medium sized notebook
  • Wallet
  • Several smaller items (eyeglass case, another smaller makeup bag, etc)

Unlike the Alto, the Mezzo does have a zipper.



Width: 20 in

Length: 6.25 in

Height: 14 in

Alto is the largest Cabas bag. At 20 inches wide and 14 inches deep, it’s an ideal size for an overnight, beach, or school bag. It could easily fit a large item (extra set of clothes, beach towel, or laptop) and still have room for several more smaller items.

While it would work as a carry-on, keep in mind that the Alto does not have a zipper. There’s always a risk that your things could fall out of the bag if you’re asked to put it in an overhead bin on your flight.


The Keepall comes in 4 sizes: 45, 50, 55, 60.

To help you get a better idea of the amount you can pack into each bag, you’ll find a potential packing list of items that would fit into each bag. However, each person has a unique packing style, and these lists are meant to be guidelines - not guarantees.

Keepall 45


Width: 17.7 in.

Length: 7.9 in.

Height: 10.6 in.

The 45 is the smallest of the Keepall luggage collection, and the perfect size bag for an overnight stay or a trip to the gym. If you’re a light packer, you may get away with using it for a weekend trip - but we’d recommend going with a larger size. The Keepall 45 does meet size requirements for carry-ons for most airlines.

Here’s what you could fit into a Keepall 45:

  • Pair of jeans
  • Sweater
  • Couple of shirts
  • Pair of shoes
  • Medium sized makeup bag
  • Smaller toiletries

Keepall 50


Width: 19.7 in.

Length: 8.7 in.

Height: 11.4 in.

The Keepall 50 gives you an extra inch in width, length, and height than the 45. While it seems insignificant, you’d be surprised how much of a difference it makes in carrying capacity. The 50 is the better option for a weekend trip and will give you some wiggle room for a few smaller items. As with the Keepall 45, the 50 also meets the size requirements for carry-on luggage for a majority of airlines.

Here’s what you could fit into a Keepall 50:

  • 2 pairs of pants
  • 2 lightweight sweatshirts
  • A few tops
  • 2 pairs of shoes
  • Make-up bag
  • Toiletries
  • Full size lotion
  • Curling iron

Keepall 55


Width: 21.7 in.

Length: 9.4 in.

Height: 12.2 in.

The Keepall 55 is largest of the Keepall collection that meets carry on size requirements for most major airlines. But, don’t worry - this bag can easy get you through a 3-4 day trip.

Here’s what you can fit into a Keepall 55:

  • 4 pairs of pants
  • 2 sweaters
  • A lightweight coat
  • Several tops
  • Large/medium makeup bag
  • Full-size toiletries
  • 2 pairs of shoes
  • Curling iron

Keepall 60


Width: 23.6 in.

Length: 10.2 in.

Height: 13 in.

The 60 is the largest Keepall and is too large to meet the carry-on requirements for most airlines. However, if you typically take week-long trips, this bag is your best bet. You can get a weeks worth of clothes into the Keepall 60 and still have a little room to spare for an extra pair of shoes and accessories.

Here’s what you can fit into a Keepall 60:

  • 5 pairs of jeans
  • 8 tops
  • 3 sweaters
  • A lightweight coat
  • Large make-up bag
  • Curling iron
  • Full size toiletries
  • 3 pairs of shoes
  • Additional accessories (belts, extra purse, jewelry)


The Neverfull comes in 3 sizes: PM, MM, GM

Neverfull PM


Width: 11.4 in.

Length: 5.1 in.

Height: 8.7 in.

The PM is the smallest of the Neverfull line but is has plenty of room for the necessities. It’s ideal for someone who likes enough room for a few “extras” without having to carry a huge bag.

You’ll have no problem carrying a large wallet, sunglass case, small makeup bag, hand lotion, and even a small tablet in the Neverfull PM.

Neverfull MM


Width: 12.6 in.

Length: 6.7 in.

Height: 11.4 in.

The MM gives you roughly an extra inch in width and length and almost 2 extra inches in height. Along with the basics mentioned above, you can fit a few additional items into the Neverfull MM - like a large pair of headphones, a full-size iPad, and a small notebook.

Neverfull GM


Width: 15.7 in.

Length: 7.9 in.

Height: 13 in.

The GM is the largest bag in the Neverfull line. With roughly two additional inches in width, length, and height, the GM is much larger compared to the PM and MM. It’s the perfect bag for work, as it can easily fit a MacBook, its charger, a notebook, wallet, and small makeup bag.

It could also serve as a great overnight or bag with plenty of room for an extra pair of clothes and shoes. Like the Cabas Alto, the Neverfull GM does not a have a zipper, so use caution if you use it as a carry on bag. If you’re asked to put it in an overhead bin on your flight, your things could fall out.


The Speedy comes in 4 sizes: 25, 30, 35, 40

Speedy 25


Width: 9.8 in.

Length: 5.9 in.

Height: 7.5 in.

The Speedy 25 is the perfect everyday bag. With a width of almost 10 inches, there’s plenty of room for all the necessities. You can easily fit a large wallet, sunglass case, small hand lotion, small makeup bag, and cell phone.

Speedy 30


Width: 11.8 in.

Length: 6.7 in.

Height: 8.3 in.

With an extra inch in length and height and an additional 2 in width, the Speedy 30 is ideal for someone who needs to carry a few larger items in addition to the necessities. There’s enough room for small books, a water bottle, and a small umbrella.

Speedy 35


Width: 13.8 in.

Length: 7.1 in.

Height: 9.1 in.

The Speedy 35 is a large bag, but could still serve well as an everyday bag if you like to carry several larger items. It can easily hold all the necessities, a notebook, a small makeup bag, water bottle, tablet, and even an extra pair of flats.

If you carry a laptop, the Speedy 35 isn’t the best choice. An average sized laptop will not fit into the Speedy 35, but an iPad will with room to spare.

It’s a great carry on if you like to travel with several magazines, books, water bottle, and snacks.

Speedy 40


Width: 15.7 in.

Length: 7.5 in.

Height: 9.8 in.

The biggest difference between the Speedy 35 and 40 is the extra 2 inches in width. If you want to use a Speedy as an overnight bag, the 40 is your best bet.

The Speedy 40 can be used as a work bag, as it will fit a 13-15 inch laptop. However, those who carry the Speedy 40 have said that while a laptop fits, it looks awkward and makes the bag feel too heavy.

The 40 will work well as an overnight bag. You can back a pair of shoes, two shirts, a pair of pants, a makeup bag, undergarments, and a curling iron.

Think Beyond Size When Shopping for Your Louis Vuitton Bag:

Choosing the right size is important, but there are other important considerations to think through before you choose the right bag.

While you may feel drawn to a bag because of its style, it’s important to think about all the ways you’ll need to use your bag.

For example, do you need a bag that can serve as a gym bag and an occasional carry on? If so, the Cabas Mezzo may not be the best choice because it doesn’t have a zipper, and you may want to consider the Speedy instead.

Final advice:

When in doubt, go up a size. It’s better to have too much room than not enough.
