How to Choose a Camera Cube Size for Your Bag

Quick Answer

Match the cube's depth and footprint to your bag before you compare liters. If your bag has a dedicated cube sleeve, buy the cube made for it; otherwise measure the internal depth, width, and height, then choose the smallest cube that holds your camera with the lens attached. For a medium-format body or a gripped camera, start with the Long Weekend Morro Camera Cube - 8L, which is slightly deeper than many compact cubes.

Measure Your Bag Before You Shop

Open your bag and measure the internal depth, width, and height at the point where the cube will sit. Depth is the number that eliminates the most options: a cube that is too deep will not let the bag close, and one that is too shallow leaves your camera rattling around. Also note whether the bag has a dedicated cube opening or sleeve. A cube designed for a specific backpack, like the Long Weekend Morro Camera Cube - 8L, which fits perfectly inside the Long Weekend Morro Backpack, will line up with those access doors instead of fighting them.

Capacity: Liters Are a Starting Point, Not a Rule

Cube liters describe volume, but the shape of that volume matters more. A cube with a full panel zipper opening, such as the Morro 8L, lets you load and organize gear quickly because the whole front opens flat. A cube with a smaller lid opening may hold the same volume but be harder to pack. Use liters to compare cubes of similar shape, then check the listed depth against your bag measurement. If the product page does not list internal dimensions, treat that as a decision limitation and look for a cube with published measurements instead of guessing.

Camera Cube Buying Guide: What to Check in Order

Work through these checks in sequence so you do not buy a cube that fails on a basic fit. Each step removes options quickly and leaves you with a short list.

Bag compatibility: Does the cube fit a sleeve or opening your bag already has? If yes, buy that cube first.
Depth: Measure your bag's internal depth. Choose a cube at or just under that number.
Gear footprint: Will your camera with the lens attached fit inside the cube's width and height?
Access style: Full panel opening for fast packing and organizing; smaller openings for lighter carry.
Protection and organization: Dividers, filter storage, and strap management add bulk but reduce setup time.

When to Size Up or Down

Size up when you carry a medium-format body, a camera with a battery grip, or more than one lens. The 8L Morro is slightly deeper than many compact camera cubes and can carry most medium format setups, so it is the safer starting point for that gear. Size down when you shoot a point-and-shoot or a single compact camera and want the bag to stay slim. In that case, a smaller cube plus a wrist strap keeps the kit light and easy to pull out.

Camera Cube Size Decision Rules

Rule 1: Dedicated sleeve wins: If your bag has a cube sleeve or access doors, buy the cube made for that bag. The Long Weekend Morro Camera Cube - 8L is designed to fit perfectly inside the Long Weekend Morro Backpack and its doors tuck into the backpack's access doors for one-zipper access. Skip generic sizing when a direct-fit cube exists.
Rule 2: Depth before liters: Measure your bag's internal depth. A cube that is too deep prevents closure; too shallow lets gear move. The Morro 8L is slightly deeper than many compact cubes, so it suits medium format and gripped bodies but may be too deep for slim bags. If depth is close, choose the shallower cube.
Rule 3: Match access style to how you shoot: A full panel zipper opening, like the Morro 8L, is faster for loading and organizing. Smaller openings are lighter but slower. If you carry filters, a Moment Soft Filter Case in 4 or 6 slots adds organization but takes space. Prioritize access speed if you change gear often.
Rule 4: Size down for compact kits: For a point-and-shoot or single compact camera, a smaller cube plus a Long Weekend Camera Wrist Strap keeps the kit light. The wrist strap is designed for point and shoot cameras and is easy to adjust. Do not buy depth you will not use.
