Buying Guide: How to Pick the Right Plastic Ruler for School
I remember my first school supply list and how simple the “ruler” requirement seemed. But when I got to the store, I was faced with a whole aisle of options. It turns out, not all plastic rulers are created equal. Choosing the right one can make a big difference in a student’s day. Here’s what I look for when picking out the best plastic rulers for school.
First, let’s talk about durability. School supplies live a tough life, tossed in backpacks and dropped on floors. A flimsy ruler will snap in no time. I always look for rulers made from a sturdy, flexible plastic that can take a bend without breaking. Materials like polystyrene or acrylic are often good bets. A thicker ruler, rather than a super thin one, usually holds up better over the school year.
Next, consider the markings. The numbers and lines need to be clear, sharp, and most importantly, permanent. There’s nothing worse than the measurement lines rubbing off after a few weeks. I prefer rulers with engraved or printed markings that are fused into the plastic. Check for a double-sided design with both inches and centimeters. For younger students, having large, easy-to-read numbers is a huge help. Some rulers even have raised edges, which are fantastic because they prevent ink smudges when you’re drawing a straight line.
Length is another key factor. The standard 12-inch (30 cm) ruler is the most versatile and fits perfectly in a pencil case. However, a 6-inch ruler can be a great, compact option for younger kids or for keeping in a small math kit. I also think about transparency. A see-through plastic ruler is my personal favorite because it allows you to see the paper underneath, making it easier to line up measurements accurately with text or diagrams.
Finally, don’t forget the little extras. A hole in one end can be surprisingly useful for hanging the ruler on a hook or storing it on a binder ring. A non-slip backing is a nice feature that keeps the ruler from sliding around while you’re using it. And for geometry class, a ruler that includes protractor markings or other geometric shapes printed on it can be a real multi-tool. By thinking about these factors—durability, clear markings, practical length, and helpful features—you can find a plastic ruler that will be a reliable tool for the entire school year.
FAQ
What is the most common and useful ruler length for school?
The 12-inch (or 30-centimeter) ruler is by far the most common and useful length for general school use. It’s long enough to measure standard sheets of paper and complete most math and art assignments, yet it’s still compact enough to fit easily in a pencil case or backpack pocket. For younger students in early grades, a shorter 6-inch ruler can sometimes be easier for them to handle.
Why are some plastic rulers see-through?
See-through or transparent plastic rulers are designed that way for better accuracy. When you can see the paper and the lines you’ve already drawn through the ruler, it’s much easier to align your ruler perfectly for drawing a new straight line or taking a precise measurement. This is especially helpful in subjects like drafting, art, and geometry where precision matters.
How can I prevent the measurement markings from rubbing off?
To keep the markings on your ruler from fading, look for one with engraved lines or with markings that are printed under a protective coating. Avoid using harsh erasers or abrasive cleaners on the surface. If you’re concerned about longevity, investing in a slightly more expensive ruler from a known brand often means better quality printing that will last.
Are there any safety features I should look for in a school ruler?
For very young children, a ruler with rounded, smooth edges is the safest option to prevent any pokes or scratches. You also want to make sure the plastic is flexible and not brittle, as a brittle ruler can snap and create sharp edges. Generally, the rulers marketed as school supplies are designed with these basic safety considerations in mind.
Can a plastic ruler be used as a straight edge for cutting?
While you can use a sturdy plastic ruler as a guide for tearing paper, I would not recommend using it with a craft knife or box cutter. The metal blade can easily bite into the plastic, damaging the ruler and creating an uneven edge. More importantly, the blade can slip, which is a safety hazard. For cutting with a sharp blade, a metal ruler is a much safer and more effective tool.
What makes a good plastic ruler for a left-handed student?
The good news is that most basic plastic rulers work equally well for both right and left-handed users. However, a transparent ruler is particularly helpful because it eliminates any visual obstruction. If the ruler has measurement numbers only on one side, just check that the student can read them comfortably from their natural working angle. For the best plastic rulers for school, ambidextrous design is usually a standard feature.
