If you are in dilemma about the feasibility as well as usability of fluid design and fixed design, the discussion below citing differences between these two designs with focus on their respective advantages and disadvantages will best guide you.
Fluid design is an interface between scalable design and responsive design. Fluid design agrees with percentage based dimensions to make width of images and tables adaptable to the dimensions of the screens where they are displayed. Though the layout of websites with fluid design is not flexibly altered, such websites feature free flow of content that fills in the space available on screens. Evidently, fluid design is a feasible solution to the problems associated with the display of text-rich websites as there is no pull on the content flow.
Fluid designs best work in combination with responsive templates. The combination of fluid designs and responsive templates allows greater adaptability of images and tables according varying screen sizes. Even if not coupled with a responsive template, fluid design allows optimization for mobile displays to a great extent. A piece of fluid design if left uncontrolled becomes too wide to fit in on a screen that reduces readability of content by far. Fluid designs are suitable for websites with simple layouts and free flow of content.
Limits to whitespace on a webpage or interface due to free content flow make the use of fluid designs a disadvantage. Reduced whitespace makes reading of text a difficult task that repels and drives away the audience. If this downside is taken care of, these designs make user-friendly websites. With a control over the free flow of content, the look and feel of text with fair amount of readability can be maintained. It reduces scrolling too ensuring convenience for the user.
Websites with fixed design have both advantages and disadvantages. Fixed design lacks flexibility and fluidity that takes away control from over customization of websites. Non-customizable websites remain stagnant and thereby go out of the fashion. Fixed design comes with minimum user control over websites. What is the most advantageous about using fixed design is freedom of white space. Maximum whitespace helps with readability of content, which is a user-friendly aspect. Fixed design facilitates proper planning of whitespace attributing a clean look and feel to websites.
But, websites with fixed templates appear dwarfed in large browser windows due to lack of responsiveness. As fixed templates lack responsive design, websites cannot adapt to the varying screen sizes and different browser windows. Such websites are not suitable for mobile device users, and therefore not profitable for a business whose target audience belongs to the touch-screen generation. These days, fixed design has little space in the virtual world.
To be precise, websites with fluid design are more advantageous than fixed design for businesses.
