How to Square Up a Piece of Plywood

Even if you measure precisely when cutting the pieces of wood, getting them ‘square’ can be a challenge since an even cut may still vary from perfectly straight. In this blog post, we’ll walk you through a few simple steps that will help you square up a piece of plywood for your next DIY project!

Tools You Will Need

  • Straight edge
  • Table saw
  • Circular saw
  • Measuring tape
  • Pencil
  • Clamps (optional)

5 Steps on How to Square Up a Piece of Plywood

1. Measure the Length of Your Plywood

When starting a project involving plywood, it is important to properly square up the material. 

To accomplish this, begin by measuring the length of your plywood with a tape measure and marking it at each end with a pencil. This will provide you with a reference point of how long the plywood should be once squared up. Next, use a combination square or tri-square and draw a line on all four corners from your marked points, one edge at a time. 

Measuring the Length of Your Plywood

Check for square using the 3-4-5 rule or Pythagorean theorem; if both legs of your triangle equal 55 inches then your plywood is correctly squared up. Remember to measure twice and cut once!

2. Place the Straight Edge

Squaring up a piece of plywood is essential for accuracy when creating furniture or other projects that involve the use of this material. The first step involves placing a straight edge along one side of the plywood. Ensure that the straight edge is securely in place and then run it along the length of your workpiece. You should expect to feel some resistance, as the edge should be pushed hard against the wood to get an accurate reading. 

Pay close attention to any bumps or waves that you may feel as you run your straight edge against your plywood’s surface. If you feel any imperfections, use sandpaper in conjunction with your straightedge to even out these irregularities until you achieve a perfectly flat and square surface.

3. Cut the Piece

If you have a piece of plywood and need to square it up, the best way to do it is with a table saw or circular saw. When making this cut, it’s important to be precise and follow the safety instructions for your tool exactly. Make sure the blade guide is securely in place and set it so that you are only cutting 1/8 inch deeper than the surface of your piece. 

Adjust the position of the fence so that when you pass the material through, it runs parallel to the marked line on the board. Use steady, even pressure as you move along with every stroke to ensure accuracy in cutting, and stop often to check how straight your edge is looking. When you’re finished, take a minute to double-check that everything looks good before moving on with your project.

4. Adjust the Saw

It is important to check that a cut piece of plywood matches its initial measurement to achieve the desired results. When measuring the piece after it has been cut, small differences can easily be corrected by adjusting the saw before repeating the process with the same lengths in mind. Through careful measuring and re-adjusting, one can Square Up a Piece of Plywood effectively and reliably so that they are confident in their project’s outcome.

5. Make Additional Cuts or Adjustments

Squaring up a piece of plywood is an achievable task for any DIYer. After cutting it to the desired size and shape, clamps can be used to firmly keep the plywood in position to allow for more precise adjustments. Making sure that the sides are parallel and at 90 degrees with one another could be accomplished by the use of a combination square. 

Furthermore, if accuracy is important a small carpenter’s level could be employed to ensure everything is lined up properly before moving on to the final assembly. With these tools and techniques, it is possible to obtain reliable results when squaring up a piece of plywood.

Tips on Squaring Up a Piece of Plywood

  1. Place the plywood on a level surface.
  2. Measure the length and width of the plywood.
  3. Mark the center of each side of the plywood with a pencil.
  4. Draw a line from each corner of the plywood to the corresponding center mark.
  5. Cut along each of the lines with a saw.
  6. Place the four pieces of plywood together so that the cut edges form a square.
  7. Drill pilot holes through the corners of the square.
  8. Screw the four pieces of plywood together with screws.
  9. Trim any excess screw length with a saw.
  10. Sand the edges of the square to smooth them out.

With these easy steps, anyone can Square Up a Piece of Plywood in no time and achieve accurate results. Proper care should always be taken when using power tools for safety reasons, but with patience and attention to detail, it is possible to complete any project with precision.  

Furthermore, having the right tools on hand can help make this process even smoother. Have fun and get creative with your woodworking projects!  Good luck!

Prepping Your Plywood: Tips on How to Square It Up Right

Plywood is one of the most widely used materials for construction and DIY projects. It’s essential to ensure that your plywood is squared up correctly to get the best out of it and have a successful project outcome. The first step is to mark diagonal lines from each corner, then measure the distance between them for accuracy. 

If the measurements are equal, you know your square is perfectly straight — if not, adjust accordingly with a plane or orbital sander. To help minimize any warping, store your prepped plywood on a flat surface until it’s ready to use. An even better option would be to keep it in an area away from direct sunlight, as this could cause excess heat which could warp the wood over time. Following these tips while prepping your plywood will give you precision results every time!

An Expert’s Checklist for Making Sure You Squared Up Your Plywood Perfectly

Making sure your plywood is squared up perfectly is not a herculean task, but it does require some careful planning, patience, and attention to detail. Before beginning your project, an expert would go over this checklist. 

Ensure the surface is clean and free from dust and debris. Draw a chalk line across the plywood. Use a spirit level to check that each corner has 90 degrees of angle. 

Make sure any saw you use is fitted with a new blade. Measure the angles to confirm they meet your specifications, check the cross cuts to make sure they fit properly into each section of plywood and finally sand down any rough edges. 

By taking these steps you can be confident that it will deliver polished results once you start building your project using adequately squared-up plywood.

How to Make a Perfectly Formed Box Out of One Piece of Plywood?

Constructing a perfectly-formed box out of one piece of plywood may seem like a daunting task but it is quite easy with the right tools and instructions. For this project, you will need a table saw, a band saw, and a 360 degree angle ruler. To begin, place the plywood sheet on the table saw and use the ruler to make four cuts: two wide-side cuts and two short-end cuts. 

Next, you need to create the four corner posts by cutting along the edge of each panel at an angle of forty-five degrees. 

You can then use a flathead screwdriver to assemble the pieces and form angles at each post’s top inside corner before manipulating them into their final position. Finally, you must use wood glue to affix each panel to create an impeccable box that has been crafted from one single piece of plywood.

How to Achieve Professional Results When Squaring Up Plywood?

Working with plywood is an art form that requires precise measurements to achieve a truly professional finish. For starters, you should always try to pick the best quality sheet of plywood available so that you can begin with a piece that’s straight and true. To ensure an even cut, use a good sharp saw blade designed for cutting hardwoods, and do not make many passes as this can cause jagged edges – one pass should be plenty. 

Use a Good Sharp Saw Blade

Measure twice before you cut, as accuracy is fundamental in achieving professional results in squaring up plywood. Additionally, if your piece requires multiple cuts, mark each of them carefully and always allow some extra length when measuring to ensure accuracy. With these tips in mind and a little practice, you can attain professional-level results when squaring up any type of plywood.


It’s really easy to square up a piece of plywood using this method. You should carefully determine how to square up a piece of plywood. Make sure you have a good quality level and take your time. In no time at all, you’ll have perfectly squared plywood that’s ready to use for whatever project you’re working on.
