Since you are just done with degree show and plan to design a portfolio to kickstart your career so i thought about writing on this topic.
A key decision that you will make as you create the portfolio relates to the
format. You will be carrying your portfolio in taxi cabs, automobiles, trains,
buses, and airplanes. They will be laid out on conference tables and desks, and
possibly even be mailed across the country.
Although a common format size for boards and drawings is 20 inches by 30 inches, portfolios are actually becoming smaller in size.
The 20 inch by 30 inch format works well for the preparation of drawings and presentation boards, but it makes for a very cumbersome package to carry.
Format sizes that are easier to present and to transport are 8 inches by 10 inches, 11 inches by 14 inches, and 14 inches by 17 inches. Thus, early on, you must make a decision about the final size of your portfolio.
The larger-size formats make it easy to present original work, yet the smaller-size
formats are easier to handle. Frankly, some employers still like to see 1/4-inch scale drawings and full-sized sample boards.
You might have both large- and small-sized format items available. When you are finalizing the schedule for an interview, you can inquire about any preferences that the prospective employer may have.
