Total 6 key principles for logo design.

1. Simplicity
2. Originality
3. Versatility
4. Scalability
5. Balance & proportion
6. Timelessness

1.Simplicity

Simplicity is what helps a logo stand up against challenges of time and what makes it replicable and easy to work with. You want your logo to be as clear and visible as possible while reflecting your aesthetics and conveying your philosophy. Like as: Nike logo - nothing more than a monochrome swoosh. It doesn’t get simpler than that.

2. Originality

Your logo needs to be different enough to attract attention and memorable enough to remain in people’s minds. Think of all the unforgettable logos stashed in your memory: Apple are at the top of the list. Maybe we remember them because we see them non-stop, but perhaps it’s also because they’re original and unforgettable. Successful logos stand out from the crowd by being different, original and memorable. Your logo must attract a first glance that people will remember and then express trust and reliability upon repeat interactions.

3. Versatility

Your logo has a big job. It will adorn all of your products, shop signage, digital ads and much more (think t-shirts and bumper stickers!). So, your logo needs to be versatile and adaptable to land anywhere. Think of all the places you’ll want to use your logo and make sure it looks good in every single one of them. Having a simple, easily recognizable logo can help with versatility. Another great way to achieve versatility is with a responsive logo. Responsive logos are adaptive and have different variations of size, complexity or even color to accommodate and adapt to wherever they are placed.

4. Scalability

Similarly, your logo should be able to adapt to any size. Can it go on a giant billboard and a tiny pen? Going back to the adaptability principle, we know that your logo ought to be scalable to represent your brand anywhere. A scalable logo needs to make sense, look good and remain legible at any size—whether it is printed on a tiny business card or on a huge poster. If you include too much detail in your logo it will make it harder to scale down to a small size.

5. Balance & proportion

Humans recognize balanced designs as beautiful. A well-proportioned design will strike a balance between the various elements that make up your logo. Proportion refers to the weight of each of the elements that make up your logo. From a practical perspective, the right proportions will make your logo whole and help it to make sense. Symmetrical logos are balanced through equally weighted elements aligned on either side of a center line.

6. Timelessness

A timelessness looks just as good in ten year as it looks today. Avoid giving in to short-lived fads when designing your logo and go for a classic look. Psychedelic 70s-inspired logos might be all the rage for your industry today, but they might be played out in a year.

Epic logos stand the test of time because they pay attention to logo principles and rules that last, rather than what everyone else is doing right now.
