Major differences between a Diploma and degree:
Diploma in a layman language is a short term course generally up to 2 years which mainly focuses on training a person in a particular field.They are one of the quick and the best way to get a job as their course is based more on practicality. The importance of Diploma as compared to degree is relatively less.
DEGREE on the other hand, is a long term course which varies between 3-4 years for Bachelors, 2 years beyond Bachelor for master degree, depending on the course.Degree provide more in depth knowledge about a particular course then Diploma. Earning a degree opens more doors for opportunities as compared to Diploma. In fact, various career options require at least Bachelor degree.

This is entirely up to you whether you want to pursue a Diploma course or degree in interior design.
You should take into account the timeframe of a Diploma and a degree, the ratio between practical and theoretical knowledge and the credit requirement of the course. A Diploma course usually takes lesser time as compared to a degree course. This is because the aim of a Diploma course is not to impart general knowledge for a more rounded education, rather it focuses on specific one. Acquiring a degree opens up more promising job opportunities for a student than a Diploma or a certificate course. A number of career options require an applicant to have earned at least a Bachelor's degree and various other require more qualification than that. Diploma programmes are quite similar to certificate courses. Nowadays numerous youngsters are opting to go for Diploma programmes instead of full-fledged degree courses. Regards
