What is a Grid?
A grid, as defined by Wikipedia, is a “two-dimensional structure made up of a series of intersecting vertical and horizontal axes used to structure content. The grid serves as an armature on which a designer can organize text and images in a rational, easy to absorb manner.” (http://en.wikipedia.org/wiki/Grid_%28page_layout%29, accessed 20/01/2012) The grid is basically a set of horizontal and vertical divisions used as guidelines to organise and structure content.
Our brains are wired to make things simpler in order to make them readily understandable which is why we are compelled to impose order on things that seem chaotic. The easier it is to impose order, the quicker we can identify a pattern and move on. Grids are so organised and logical that they require hardly any interpretation.
Ratios are at the core of any well designed grid system such as the ‘Rule of Thirds’ and the ‘Golden Ratio.’ These ratios are everywhere in modern society and it is using them successfully in a grid system that can determine whether a design functions properly and is aesthetically pleasing.
A Brief History:
The use of grids can be traced back hundreds of years with evidence of grid systems being utilised as early as medieval times. These were used for writing the hand copied books of the Middle Ages and were based on optimal proportions. An example of such a grid system is ‘Villards Diagram.’

The modern grid system did not appear until after World War II when a group of graphic designers, many of whom taught at the famous Bauhaus school, began to question the relevance of the conventional page layout of the time resulting in a more flexible system helping designers achieve coherency in organising the page. The overall outcome was the typographic grid which today is associated with the International Typographic Style.
The Advantages of Grids
The advantages of using grids for design are numerous. In his book, Ordering Disorder Grid Principles for Web Design, Khoi Vinh describes the major advantages as:
- Grids add order, continuity and harmony to the presentation of information.
- Grids allow an audience to predict where to find information, which aids in the communication of that information.
- Grids make it easier to add new content in a manner consistent with the overall vision of the original presentation.
- Grids facilitate collaboration on the design of a single solution without compromising the overall vision of that solution.
While grid systems have seen significant use in print media, it was not until recently that the use of grids in website design has exploded in popularity.
How are Grids used in Web-Design?
Design for the screen poses unique challenges. Grid design and frameworks need to be flexible because information is variable and subject to viewer selection. There are many grid system frameworks available for use, the more popular being the 960 Grid System. There are also many online tools which will assist a designer in creating a custom, flexible and semantic grid system to use.
The 960 Grid System is 960 pixels wide and comes in two primary variants, a 12 column and a 16 column grid. The grid system effectively is a CSS framework 960 pixels wide. This width was chosen because it fits nicely on a large majority of screens which have 1024 pixel wide displays and because 960 is easily divisible allowing whole numbers when factoring in column widths and margins.
By organising visual communication with a grid system, the designer hopes to create strong interrelationships between the typographic and visual elements. A grid is a system designed to assist designers in creativity and organisation of content and in no way should be used as a fixed system. A grid must be flexible and seen as a “springboard for creativity”– Khoi Vinh.
“To say a grid is limiting is to say that language is limiting, or typography is limiting.”– Ellen Lupton, 2009.
Below is an example of a restaurant business website which utilises grids in its design:

Pizza-Express Homepage

Pizza-Express Homepage Grids
Pizzaexpress.com is a good example of a website using a grid system. The website utilises a 6 column grid 940px wide even though the overall site is 956px wide. This is close to the widely used 960 grid system and means the whole site width will display on a 1024px screen. Each column is 140px with a 20px gutter (displayed in white on the screenshot).
On first entering the website, the grid is not immediately visible. This is due to the interactive CSS3 slider which scrolls through images of pizzas and other dishes taking up all the screen space above the fold. (The fold is shown as a yellow dashed line on the screenshot). However, once the user scrolls down, the grid layout becomes more apparent. The grid assists in the lining up of content horizontally throughout the page and ensures spacing (gutter) between elements is equal.
In addition, the grid helps ensure the different content elements are an appropriate size. For example, the ‘Find, Book or Order Online’ section found just below the fold on the left is 4 columns wide including the gutters. The ‘Our Food’ and ‘Offers Worth Sharing’ sections found immediately below are both 2 columns each and have a gutter between them. Both of these sections together add up to the same width as the ‘Find, Book or Order Online’ section found directly above. This strongly affects the continuity and the visual balance of the site, making it more appealing and clearer for the user to interpret, understand and experience.
It also creates a visual hierarchy of content elements. As a user scrolls below the fold, the ‘Find, Book or Order Online’ section will be the next object to draw his or her attention. This is because this section is the next biggest element on the page and is also a direct call to action for the user to find a restaurant nearby. The typography styling in this section and the fact that the web designer has made the heading bigger for this part further reinforces the visual hierarchy and that this section is more important than the ‘Pizza Express on Facebook’ section which is on the same level on the page.
Branding and the navigation menu span across the top and whole width of the website. The restaurant’s logo is slightly to the left of the grid lines and therefore off the grid. This in turn emphasises the restaurant branding (logo) and the website’s navigation resulting in a more apparent usability experience. Also, its placement in the top left hand corner of the website continues to emphasise branding and brand awareness to the user. This is encouraged because people in the ‘Western’ world read from left to right, top to bottom and therefore an object placed top left on a webpage is often the first element to be seen by a user.
Below the navigation, there is a clear call to action where a user can search for a restaurant nearby and download the menu. This section of the content takes up the whole width of the page filling all four columns clearly creating visual hierarchy against the rest of the page’s content. Moreover, the off grid section further reinforces the call to action as do the extremely noticeable pink coloured buttons against a black background.
The negative (white) spacing of the gutters between columns and the overall layout of content elements have a strong positive effect on the content’s legibility and user’s understanding.
The website, utilises different grids systems throughout the pages depending on the different types of content. This perhaps is not the best idea as a grid should be constant throughout so users can predict where content is going to be as they navigate through the website.

Pizza-Express 'Our Food' Page

Pizza-Express 'Our-Food' Page Grids
The ‘Our Food’ > ‘Discover’ page employs a 4 column grid system with a 12px gutter. The branding, navigation bar, ‘Find a Restaurant’ search and ‘Download Menu’ buttons remain in the same position at the top of the page and provide a clear, easily identifiable and continuous user interface.
Following on down the page, another section titled ‘The New Stars of Pizza Express’ can be seen half above the fold and half below encouraging the user to scroll down. This section can also be seen on the homepage however it only occupies 2 columns from the grid whereas on this page, it can clearly be identified as the main content as it fills 4 columns, the whole page width. The actual content inside the section is not aligned to the grid lines emphasising the photos and paragraphs of text about the restaurant’s dishes.
Below this, 4 individual sections can be seen relating to the restaurant’s different menus. Here, the grid is being used to present the content horizontally (on the grid) as each section fills a whole column from the grid. These individual sections are then wrapped in a border and headed ‘Discover Our Menus’ presenting them as one section overall.
Negative (white) spacing is being utilised again to emphasise the section and almost mirror the white gaps of the top third of the webpage. This, consecutively emphasises the ‘New Stars of Pizza Express’ section by enclosing it in a thick white border.
The web pages containing the menu use the same 6 column grid system as the homepage. The branding, navigation, ‘Find a Restaurant’ and ‘Download Menu’ call to action sections are again present where expected at the top of the page, further reinforcing the continuity of the user interface.

Pizza-Express 'Menu' Page Grids
Below this, the menu can be seen clearly divided into 3 columns with the content aligned to the left. Headings are emphasised as they are the largest type on the menu and placed in a Serif font therefore creating visual hierarchy and making the content more legible and clearer to understand. The dish names are also found in a Serif font but slightly smaller than the heading. In addition they are styled in the same pink colour as the call to action buttons found below the navigation creating continuity through the website’s colour scheme and making it aesthetically pleasing. Dish descriptions are found in a Sans Serif font and much smaller than the dish names showing the third level of hierarchy through the text size.

Menu Close-Up
The alignment of the menu items on the grid makes a much more visually appealing and balanced page. If these items were placed haphazardly on the page, the menu would be illegible and the user would get extremely frustrated when trying to read through. The grid further assists in creating visual balance by aligning menu items to the top of the page and listing them.
It is clear this page is extremely content rich containing not only menu items and dishes, but also links to reviews from celebrities. Further emphasis is placed on certain dishes by placing them in a pink coloured box. In addition, as a user scrolls down, black boxes appear within the menu containing photos and headings concerning reviews from celebrities. These boxes are emphasised by their high contrast typography, beautiful imagery and the white spacing all around. Both the menu item boxes and celebrity review boxes are aligned to the grid as well ensuring the visual continuity of the lines as a user reads and scrolls down the page.

Pizza-Express 'Desserts' Page Grids
The ‘Desserts’ page again utilises the same 6 column grid as the previous menu page and the home page. This continuity in content layout makes it easy for a user to identify the content he or she might want to read. In addition, the navigation is in the same place as before as is the ‘Find a Restaurant’ and ‘Download Menu’ call to action section. Again, this continuity in layout and navigation ensures easy functionality of the site and reinforces a good user experience.
In addition, the grid layout of this website helps enhance the brand image and identity of the restaurant and assists in providing credibility to the content and business. Ensuring the content lines up on a grid system not only makes it more legible and easier for the user to skim through and find the content he or she is looking for, it also assists in providing visual balance, emphasis where it is needed, a positive effect on legibility, usability, accessibility and an overall better user experience.
As a result, the website appears more professional which gives the content credibility and the user a sense of security. This is extremely important when creating a website online because effectively anyone with the knowledge to build a website can publish content online. Once again, from his book Ordering Disorder Grid Principles for Web Design, Khoi Vinh says “If a user encounters some evidence that there is order in place, his confidence in and sense of ease with the system increases dramatically.”
This is extremely important as, very often the user does not know the source of the content on a webpage. However, if the page looks good, is well laid out, and so on, it gives a professional feel and look to it therefore reinforcing the credibility of content and putting the user at ease.
Conclusion
Overall, even though one restaurant’s website has been discussed, it is apparent that many of the more professional and successful restaurants and businesses utilise grid systems on their websites. A grid is an extremely useful and powerful tool, however great care should be taken at the start of a web design project when designing the grid.
“A grid is only useful if it is derived from the material it is intended to handle.” – Derek Birdsall, Notes on Book Design.
Furthermore, Khoi Vinh also says “ when we use a grid for the Web, we must be responsive to our users, we must create experiences around the fact that they will not just consume them but also use them, and so we must take into account the grids behavioural dimension as much as its formal dimensions. We must also keep in mind that the grid is not a tool to impose order on users or to usurp their control; it is a tool to impart order to our users so they can create their own experiences.”
Here, Khoi Vinh is basically saying that the user is not just going to read a website, he is going to interact and negotiate the information being portrayed for himself. For this reason, a grid must not be overly complicated and instead should be kept ‘everyday’ simple. In other words, a web designer should not design the content layout in a way that he believes people should look at it, but keep it basic so that the user can interpret the content provided in a way he or she wants to.
In general, grids are used to line-up and present visual content in an orderly and logical manner to support a good user experience. In addition, a grid assists in the creation of a visually balanced website which is paramount in helping a user to understand the content and interpret it correctly and effectively.
In addition, a grid allows emphasis to be placed on content by ensuring the object to be emphasised is placed off the grid. This method of emphasis is extremely useful and also very aesthetically pleasing when used effectively. A grid can also guide a user into the content and guarantee it is clearly legible and accessible by ensuring elements are lined up, flow correctly and found where they are expected to be.
Furthermore, a grid layout can assist in enhancing the brand image or identity and provide credibility both to the content on a website and a business overall. By ensuring a website’s content is lined up on a grid system, not only is it more legible and easier for a user to skim through to find the required information, it also assists in providing visual balance, emphasis where it is needed, a positive effect on legibility, usability, accessibility and an ultimately better user experience.
The overall result is that a website appears more professional. This in turn gives the content more credibility and makes the user happy with the information due to the sense of security gained. Arguably, this is one of the most important reasons for using a grid system as anyone with the knowledge to build a website can publish content online and users know this. So it is fundamental that a user gets a sense of security about the content, otherwise he or she will simply leave the website and disregard the information therein.
