50 characters (of which 15-25, depending on layout, are visible in the form input field) for the family name should be plenty. It's what works well for me, anyway. For consistency, one should assign the same amount for the first name(s). I decided for the number 50 a decade or so ago because the longest realistic name I could come up with ad hoc was 15 ...

In theory the correct answer is no upper limit for name lengths. Allow the user to enter whatever their name is using whatever characters are available to them so that you will never run into a circumstance where someone is prevented from entering their valid real name. In practice that is not possible to implement. There have to be limitations. These ...

Given the diversity of names, I wouldn't... set a floor or ceiling limit on name length, OR even break the name into two separate fields. Depending on the country / cultural background of a person, they may have a more Westernized [first-name] [surname] name, but they may not. Why possibly bar users from entering their complete name because of arbitrary ...

Based on the type of the application you may want to select an upper or lower limit for the names. The upper limit though a tricky approach the lower limit may be 1 char since the person may choose to write an initial instead of the complete name. If your system requires a name then obviously you wouldn't want the user to exit without entering a name at all. ...

For question 1. In the slider when you keep a step of 0.5 cms it will be an extra effort for the user to set it at a specific value on the first attempt. Moreover you will have to keep sliders with different range configurations for all the five aspects you want to capture (which you will have to do as range validations for the other two options as well) ...

For question 1, I would rule out option 2 (slider) because many people have problems with their body image. Sliding a slider to the right gives someone a perception that they are fat. People of extreme size (one way or the other) may have a greater sense that the website is not helping them, even more than if a list of sizes on a clothing site does not ...

It's better to allow non-Latin characters for two reasons: 1. For international delivery by mail, only country needs to be in Latin characters. Local post will do the job better if they'll be able to read an address in native language. 2. If address will be read by another users, it's still better to have native version, because conversion to Latin can be ...

I think that some of this will depend on the content you are actually looking at displaying. For example, if this is something like choosing a country from a list, there are some better ways of handling it (for example) than just a regular dropdown. In general, the better user experience is when the user isn't hidden so much content. This article and this ...

Take a look at this article about web form usability: http://uxdesign.smashingmagazine.com/2011/11/08/extensive-guide-web-form-usability/ The choice of label alignment highly depends on the length of your form and whether your user should fill out all fields. Typically for longer forms (5+ fields) where user should fill everything out, you want to place ...

I believe the best option will be to keep the length of all input fields the same, and on a grid, aligning them with the top menu, as you say. Also, the blank space on the right shouldn't be a problem, as it helps in emphasizing the inputs anyway. It anyway is a matter of choice and what improves usability. Hope this helps.

I like the idea of sliders from Franchesca. One slightly different approach would be using connected sliders like used by Humblebundle. It was totally usable for me from the very first moment: Connected means, that if you change the value on one slide (per slider or textbox) all other values are getting equally changed as well.

Have you seen the slider controls often used in graphics packages for creating colour gradients? You could have a single slider control where you can drag and drop currencies onto the slide bar (like the very bottom bar on the graphic). The slider control represents 100%, so a single currency dropped onto it has no moveable slider boundary. Adding a 2nd ...
