Non-designers Essential Glossary of Design Terms

Every industry, business and profession has its own language and that language can leave you feeling confused and result in lots of misunderstandings.  We thought you might find our Design Terms Glossary useful whether you are using the training in our Members’ section or dealing with a graphic designer directly.





JPEG stands for Joint Photographic Experts Group and is used mainly for compressing photographs into digital images.

The greater the number of pixels the higher the quality of the image, but the bigger the file size and vice-versa.

Important Note:

Once an original photo has been saved into a lower resolution format it is NOT REVERSIBLE so always keep your originals safe (and in their original format) and work with copies only.

Remember even if you save a low resolution image into a high resolution format it WILL STILL BE low resolution.

Justifying is a term applied to type.

There are four main ways to align type on a page.

Range Left has all the type in a neat vertical line on the left and a ragged edge on the right.

Range Right has all the type in a neat vertical line on the right and a ragged edge on the left.

Centred type is vertically aligned down the centre of the type leaving matching ragged edges on both left and right.

Justified type has its letter spacing adjusted so that both left and right vertical edges are smooth and neat.

This technique is often used in books and magazines as, when dealing with large bodies of text, justifying the type makes it look neater and makes it easier for the reader.

However, when used for smaller amounts of text, justifying can result in some very odd letter spacing indeed.

Always rely on your eyes, not the computer and remember you can always adjust the odd looking spaces manually by kerning (under K in this glossary).
