You'll need a comfortable tool pouch layout for framing a house to store your tape measure, marking pencil, utility knife and hammer and a pouch to hold nails or screws comfortably within reach as you move across the job site.

Every minute you spend walking across a subfloor to find a misplaced pencil, a dropped utility knife, or the right size framing nails is wasted money and energy. Setting up a comfortable tool pouch layout for framing a house is all about creating muscle memory and saving your lower back from chronic strain.
When you get a utility belt and pouch, the only super important thing is that you like it and are comfortable with it. It will be with you anywhere from 500-2000 hours as you work on your home. Also, consider all the different aspects of the building process when buying a belt and pouch. It will be just as useful when you're tacking on vinyl siding as when you first use it for frame work.

When your tools are balanced ergonomically across your hips, you can grab exactly what you need blindly while keeping your eyes fixed safely on the workpiece. Let’s look at how to organize your rig to maximize speed and minimize body fatigue.

You can choose to go minimalistic so it's lightweight. Or you can get a big utility belt than has a gazillion pockets and has suspenders to distribute the weight.
It needs to be comfortable and a good low cost. It's whatever makes you feel empowered as a builder.
