What is the best text font for health website

[MasonBaker]

What is the good text font for health website, font size, inline spacing, character spacing etc.?

Is there any study on it? what font looks to good to eyes?  (on what font user stay for long time etc)

I personally like apple website text font.

The Helvetica font family is usually known for being the most user friendly, and easy on the eyes font for most types of website, for example, Moz is using the following for this post:

font-family: "Helvetica Neue",Helvetica,Arial,sans-serif;

There's lots of good usability info available, but the main problems are:

• text that is too small
• not enough contrast between the text and the background

Contrast isn't just a problem caused by the colour of the text (but avoid the gray on gray text!) it's also caused by the weight of the font. The vogue for thin fonts also reduces contrast and readability. To compensate the text needs to be larger.

Not everyone has the eyes of a teenager! If you can - test your designs on someone(or more than one person) who represents your target audience.

You'll also want to consider the devices/resolution that your audience will be using. (kids with smartphones vs retired people with older desktops and low resolution displays.

Also keep line length in mind - especially with responsive design.

Here's a couple of Jakob Neilsen articles on fonts, (there's lots of other guidance out there though)

Hope this helps.
