Review – Helix Architects Triangular Scale

Rulers. Well, we all need them at some point. Whether you need to draw a straight line or know the distance between two points, they come in real handy. But sometime the information you need is just not on your ordinary ruler. So you get an architect’s triangular scale. But which one? Let’s look at one of the cheapest: the Helix Architects Triangular Scale.


First off, the plastic this thing is made out of is very brittle and sharp. Little burrs and notches line the sides. There are no rounded corners, and you can easily stab yourself on the triangle points. However, there seems to be no fear of shattering or snapping in the piece, it is quite sturdy.

The information is printed in a nice, readable black over the very-slightly off-white plastic. From what I can tell (truth be told I’m not entirely sure about what all the sides are for) they are accurate. I have compared them with several other units I have. The ink used is resilient, but also raised and will rub off with prolonged use as will most rulers and the like.


Overall, for it being fairly cheap, it is a nice piece. It does its job well and will probably serve for several years before needing replacement with proper care, though there are many more comfortable or longer lasting alternatives out there.

Review – Westcott rulers

Well, when one is drawing, or drafting especially, it is useful, if not necessary, to have a ruler. And one might think that all rulers are the same. But they’re not. Some rulers have uneven edges, or mis-marked inches.


A cheap ruler might cost half a dollar, and a good one might cost a full dollar. It’s not much difference and definitely worth it. The Westcott rulers that I have here are very functional, durable, and standard. Then have straight edges and correctly marked inches. One is clear acrylic and the other is steel. I use the steel for inking and the clear for sketching. I would recommend two rulers for that reason. And these are flexible, and the markings are wear-resistant. My only real complaint would be that the acrylic ruler scratches a bit too easily.

This sounds much more like a recommendation than a review, and it is, sort of. It’s a no-brainer to get a ruler. Getting a good one is not much more expensive than a cheap one, and these work great, they’re some of the best I’ve used.
