They say that one of the tell-tale signs that you’re getting older is when your eyes just aren’t working like they used to. If you think about, we take our vision for granted and that’s because there’s rarely a moment when someone will ponder whether or not their eyesight will ever fail them. Rather, we just are under the impression that like our health, our eyes will never stray from being in good working condition and that we’ll never have to resort to glasses or contacts, or anything that we’d need to depend on to flip through the pages of a book or refrain from tripping over a fire hydrant.
Earlier this morning I had my first eye appointment and when the nurse informed me that she would be administering eyedrops, I just nodded and tilted my head back. She then informed me that my eyes would become dialated and that everything would be extremely blurry up close. Again, I just nodded and was told to return to the waiting room to wait for the Doctor. A few minutes later, my eyes became extra sensitive to light and I noticed when I moved my palm close to my face that I couldn’t see anything except for a skin-toned blur. Sitting there, with poor vision due to the eyedrops, it made me think about various concerns I’ve often thought about.
In recent years, with the advent of technology, things are only getting smaller in size including the text we read on our computer screens. Unless one were to realize this initially while developing user interfaces for those with slightly poorer vision, I believe things will only become worse.
Despite this concern, I have seen various kiosks and web sites that use larger onscreen text, but some of these are only in effect because of a trend that I call “Biggie Size”, wherein the designer has decided to use larger text because it’s the “in” thing to do, not necessarily because it might help those with poorer eyesight.
It’s certainly something to take into consideration, not only because it looks cool or earn you high fives from your peers but that it might actually be more readable for those straining their eyes because of smaller text. Yet, where do we begin as designers as far as a baseline text size for onscreen reading? There’s been several debates on this topic, many of which never really draw a specific conclusion or answer to a perfectly legible text size for any reader. There’s good reason for this, mainly the fact that unless it’s a “one size fits all” t-shirt or baseball cap, I don’t think there will ever be a golden answer to that question.
Taking that into account, this is why various web sites utilize em or percentage text scaling instead of pixel perfect (px) sizing, allowing the reader the ability to increase or decrease the onscreen text. I had a discussion the other day with my friend and fellow 9ruler Peter Flaschner, who mentioned that the font size on kartooner was too small for his tastes, so he sent me a screenshot where he increased the font size to his liking.
I had no qualms with Peter doing this, especially considering that I sized everything according to a baseline font size of “small”. Everything else is scaled according to a specific percentage, including the body text (what you’re reading now) which is set at 95% of small. I could set the percentage higher and I’ve considered it, but I’m not sure if I’ll receive a complaint that the font size is too large. It’s at this point where I’m trying to figure out how to meet the needs of those who have good vision and those whose vision isn’t quite what it used to be.
