More storage, easier to build, super sturdy, and very customizable! This garage shelving plan uses metal angle for support, increasing vertical shelf space, and distance between legs for more storage in the same footprint!  Built independent, but attached to the walls for rigidness and forward tipping, this well thought out design is a must build!

Why We Built this Garage Shelving Project

My husband asked me to design a 20' long garage shelving project for his shop.  

I've done many different garage shelving projects, and wanted to see if we could get even more storage and greater strength by changing up the materials a bit.

2x4 garage shelving

This is my original garage shelving unit.  It was so quick and easy to build, I did it all by myself in a few hours, didn't even have to cut the shelving boards.  Loved it, but how to make stronger (for a workshop), sturdier, without bulky supports?

The answer was using metal angle for the shelf supports.

Why We Love this Garage Shelving

  • Easy to build, just build the ladders, add the metal angle, and the plywood on top
  • Very sturdy and strong
  • Minimally attached to studs in walls for forward tipping prevention
  • Maximum vertical storage with shelves supports taking up less space
  • Wide clearance between vertical leg supports
  • Easy to customize in size and shape for a variety of needs
  • 1/2" plywood on shelf tops is lightweight, inexpensive and fully covers the shelf
  • Can be built against non traditional walls like metal cladding (as shown)
  • Great looking shelf, can be painted or stained

What If I Have 8' Ceilings?

You can easily adjust this plan for different size ceilings, by simply adjusting the ladder supports.  Here is a diagram with a recommendation for 6' tall garage shelving:

Why Not Flip the Angle So the Plywood Is Embedded In It?

This is a great idea, and we definitely considered it.  I ultimately choose the angle facing downward because with the 1/2" plywood, there would be a lip on the angle that could make pulling items off the shelf harder.  You could go with a 3/4" plywood but this would increase costs and weight.  Also, because the screw heads would be in between the plywood and the angle, it would create a small gap, where dirt and stuff could collect.

So we ended up going with the angle facing downward, and the plywood on top.  

 

Why 20' Long Shelving?

We choose the 20' length because the metal angle came in 20' sticks.  

You can certainly modify to different lengths but will need to cut the metal angle down to size.

If you do modify the size, consider that plywood is in 8' runs, so 16' shelving is a great choice.

Preparation

Shopping List
  • 15 - 2x4 @ 8 feet long (each support ladder uses 3 2x4x8' boards)
  • 5 - 4x8 sheets of 1/2" thick plywood
  • 8 - 1" x 1" metal angle, 1/8" thick (outside dimensions), 20 feet long
  • 100 - 3" self tapping wood screws
  • 80" - 1-5/8" metal lath screws

Shopping list is as shown in photos and video

Cut List
  • 20 - 2x4 @ 24" long, can cut at 23-7/8" if 2x4x8 boards are exactly 8' and need to consider kerf to fit cuts on 8' board length
  • 10 - 2x4 @ 8' long
  • 8 - 1"x1" metal angle, at 240" long
  • 1/2" thick plywood tops should be measured and cut to fit

Instructions

Step 1

Build ladder supports with 2x4s as shown.  The rungs should be placed 1-1/2" lower than the desired shelf heights.  

The rungs are vertical so you can screw into the angle later.  

A good span is about 5-6', so if modifying plans, build enough ladders to support these spans.

Step 2

if your space does not allow, thread the angle pieces through the ladders before installing to the wall.
 

Position the ladders along the wall for final install. Attach to studs in the wall - center ladders can be moved to land on studs.

Step 3

Place the angle inside the ladders.  

Step 4

Mark and drill holes through the angle with a metal drill bit.  Screw the angle to the 2x4 uprights on the ladders.

Step 5

Measure the inside width and rip the plywood into strips to match this width. Crosscut pieces as needed.

We did not screw the plywood down, but it can be screwed to the metal angle.

Frequently Asked Questions

Wood Questions

What kind of wood should I use?
Most of our plans use standard construction lumber like pine or fir. It's affordable, easy to work with, and easy to find. It's also rapidly renewing and biodegradable, so a great eco friendly choice!

Can I use hardwoods instead?
Yes—just keep in mind they're heavier, cost more, and can be tougher on tools and harder to join together and finish. I recommend not tackling a hardwood project until after you have built several softwood projects.

What if my boards are warped?
Choose the straightest boards at the store. You can often work around slight warps by cutting them into shorter pieces.

What wood should I use for outdoor furniture?
Use red-toned or pressure-treated 2x lumber for framing, and cedar or cedar fence pickets for the decking. Outdoor furniture should be built like a deck—your local home center can help recommend the right wood for your climate.

Will my wood move or warp after I build?
Potentially, especially in humid climates. Let your wood acclimate indoors before building. Once acclimated and kept in a stable environment, movement should be minimal. Remember, most houses are built using framing lumber - it's all about keeping moisture down indoors.

Cutting Questions

Do I need a miter saw?
A miter saw is great, creating fast, safe, and precise cuts, even for beginners. But most plans can be built with a circular saw and a straight edge. If using a circular saw to cut, take time to practice, and get good at making cuts, before cutting your project boards.

How do I get clean cuts with a circular saw?
Clamp your board, measure twice, cut slow, and use a sharp blade. This takes practice, so spend some time making cuts. I go through becoming proficient at freehand cutting in my course, it is worth taking if you want to master this skill.

Will the store cut my wood?
Yes—most stores will do rough cuts to help you transport your materials home. But from store to store, the quality of cuts could greatly vary.

Joinery Questions

What screws should I use?
We recommend star-head self tapping screws for framing, most common sizes are 2-1/2", 1-3/4". Pre-drill if close to the edge or you find your wood is splitting.

Do I have to use pocket holes?
Pocket holes are the cheapest, easiest and fastest way to do some joints - like edge to edge or a hidden fastener joint. There are other methods, but these can be time consuming and expensive. We recommend using pocket holes as indicated in plans for best results.

How do I keep things square?
Use a speed square and measure diagonals after each step. Always clamp joints before screwing to keep them tight and flush.

Finishing Questions

Stain or paint before or after building?
A quick sand before and a full finish after gives the best results. Pre-finish if you're doing two-tone or detailed finishes.

What type of finish?
Use oil-based or water-based stain. For paint, cabinet-grade latex or enamel works great. High use surfaces on indoor projects should get a coat of polyurethane, I recommend a Helsman or Spar or other flexible poly that won't crack or peel with wood movement. For exterior projects, use a finish suitable for exterior fences.

How to get a smooth finish?
Start with a well sanded project. Sand between coats (220 grit), wipe clean, and apply light coats with a foam brush or roller.

Plan Questions

Can I change the size?
Many people do, and that's the great thing about building your own furniture! But do keep in mind going bigger might mean more supports are required, and often plans are optimized for minimal material waste.

Are these beginner-friendly?
Yes—plans are written with simple tools and clear steps in mind, with every effort to make plans as simple as possible.

Can I sell what I build?
Absolutely! Just don’t resell or repost the plans themselves.

General Questions

What tools do I really need?
A drill, circular saw, tape measure, square, and a few clamps will get you through most projects.

Do I need a workshop?
Nope! A driveway or small patio is plenty to get started, just make sure you have a level place to work. If you find you are building several projects a year, creating a small workbench is a great way to store tools and have a dedicated workspace.

What if I mess up?
Wood filler, sanding, or flipping boards goes a long way. Mistakes are part of the process!

What can I do to make my projects look more professional?
Start with straight boards, make accurate cuts, clamp all joints, and line up everything neatly. Sand thoroughly, use a neutral finish, and apply it in light coats for a clean look.

I've never built anything before. Where should I start?
Start with a few smaller softwood projects to get hands-on experience. Or if you're tackling a big project, buy a little extra lumber and practice your cuts and joints first. If possible, work with someone who has a bit of experience.

Care & Maintenance

How long will my furniture last?
With good joinery and regular care, your DIY furniture can last for decades. I have pieces in my own home that are over 20 years old and still going strong! One of the best parts about DIY furniture is that it’s easy to repaint, refinish, or repair—so your projects can grow and adapt with you.

How should I care for outdoor furniture?
Lightly pressure wash or hose it down once or twice a year. Tighten screws and reapply finish as needed to protect it—just like a deck or fence. A little upkeep goes a long way in extending the life of your furniture.

How about indoor furniture?
Regularly dust or wipe with a damp cloth. If it starts to look worn, a light sanding and touch-up paint or stain can refresh it in no time. DIY pieces are meant to be durable and fixable—so don’t be afraid to give them some love now and then.
