What Is Size In Graphic Design
Size simply refers to how little or large an element is in comparison to other things in a design. In general, we employ size to emphasise or draw attention to a certain aspect. However, when combined with scale, size becomes a far more potent design tool.
What exactly is scale?
By establishing size connections between items, we may create scale within a design. If two circles of the same size were put on the same page, there would be no size connection — neither would be enormous or tiny. However, if one circle is one-third the size of the other, we would call one enormous and the other little. This is referred to as the scale of reference. If there is no scale of reference, determining the relative size of an item is impossible.
A clever use of size may create depth, tension, and movement within a design
When you grasp the technical aspect of visual development and graphic file formats, your work as a designer will be simpler and you will make better decisions. Regardless of the graphics application you choose, you must understand a few fundamentals of digital graphics. Because several of these terminology are used throughout the text, this primer is essential.
1. Start with the width and work your way up to the height.
A computer graphic’s size or dimensions are denoted by two integers, such as 720 x 540 or 1024 × 768. The first number always refers to width, while the second number always refers to height. The pixel, which is the smallest constituent of a computer image, is the unit of measurement for photographs seen online.
2. Size and resolution are not the same.
The width and height of a graphic (its dimensions) in pixels or whatever unit you are using are referred to as its size. A digital graphic’s resolution, on the other hand, might be one of two things: dots per inch (dpi) or pixels per inch (ppi). Pixels per centimetre (ppcm) is another measurement. These are dot or pixel density measures.
Number of dots per inch (dpi)
The number of dots in a linear inch is denoted by this measurement. Dots per inch are often used in printing. Up to a point, increasing the dots per inch increases the clarity of the printed picture.
Pixels per square inch (ppi)
The number of pixels in a linear inch is denoted by this measurement. A higher resolution has more pixels per inch, which results in a higher quality picture but a greater file size.
The file size of a picture is affected by both image dimensions and resolution. A file’s size grows as its dimensions and resolution grow. When generating photos for online display, you must strike a balance between image quality and file size so that the images seem beautiful while still loading fast.
3. Bitmap Images vs. Vector Images
When you understand that pictures come in two major formats: bitmap and vector, image technology becomes easy to comprehend. Vectors are formed by mathematical descriptions, while bitmaps are built up of pixels. File formats for bitmap and vector pictures are different. There are also hybrid graphic file types, which include vector and bitmap drawings.
Images in Bitmap
Bitmap graphics are built up of pixels, each of which includes colour information that makes up the picture. Photographs and scanned images are examples of bitmap graphics. Bitmaps (also known as raster images) have a fixed resolution, which means they cannot be increased in size without losing quality. This is why when you expand a little shot, it looks hazy or has jagged edges. You can’t add information that wasn’t already there. What is the takeaway? Use bitmap graphics at their original size or lower. You must begin with a huge picture if you want the image to appear at a large size.
Benefits of bitmap images:
It might be from a digital camera, a scanner, or a painting software.
Have gradation tones that are delicate.
It is possible to have a translucent backdrop (in the PNG file format)
Stock picture sites provide a large variety.
Bitmap images have the following drawbacks:
When you enlarge a picture, it becomes distorted or has jagged edges.
The file size is usually bigger than that of vector images.
Image Formats in Bitmap
JPG and PNG are the two most prevalent bitmap image formats for online display. The main distinction between the two formats is that the PNG format supports a translucent backdrop. When you view a picture with a cut-out backdrop, the region outside the shape is translucent, allowing you to see just the non-rectangular component of the graphic. Transparency data is stored in PNG files in what is known as an alpha channel, which defines whether a pixel should be rendered as opaque or transparent. Because the JPG format lacks an alpha channel, it is impossible to show a transparent backdrop in a JPG file.
Vector Illustrations
Vector graphics are shown using a set of instructions defined by mathematical formulae. The instructions guide the programme on how to create points, lines, curves, and routes. Because the visuals are constructed from instructions rather than pixels, they may be scaled to any extent without sacrificing picture quality. Vector pictures, as a result, are scalable. Vector pictures may be created using vector drawing programmes such as Adobe Illustrator, Corel Draw, and Inkscape. Vector graphics are used to produce many digital artwork and icons.
Vector pictures provide the following advantages:
Scalable—the picture retains its quality as it is expanded.
Typically, file sizes are less.
It is possible to have a translucent backdrop.
When you require several sizes of a picture, this is the way to go.
Vector image disadvantages
To develop or modify, drawing software is required.
It usually takes longer to produce.
A professional artist is required for complex illustrations.
Stock artwork has a limited selection than bitmap graphics.
Formats for Vector Images
EPS is the most prevalent vector picture format, notably on stock photo websites. The SVG format may also be mentioned. This is a more recent vector format for Web graphics that allows for interaction and animation. An XML text file defines images and associated behaviour. SVG files are not supported by older browsers.
