The Apple iPhone 6 release date is rumored for September which means that we may not get our first official glimpse at the iPhone 5s successor for several months. However, thanks to leaks and designers, consumers have been treated to a possible glimpse at the rumored iPhone 6 design and a look at how it might compare to top smartphones including the iPhone 5s, Samsung Galaxy S5 and HTC One M8.

As we approach next week’s WWDC 2014 conference in San Francisco, we’ve started to hear a whole lot about Apple’s plans for 2014, plans that the company’s Eddy Cue says represent Apple’s best product pipeline in the last 25 years. The company’s plans are said to include OS X 10.10 for Mac, iOS 8 for iPhone and iPad, the elusive iWatch, an iPad mini with Retina 2, an iPad Air 2, and of course, a brand new iPhone that’s currently being called the iPhone 6.

The names iPhone 6, iPhone Air and iPhone Pro have all been thrown around in recent weeks but the story is the same. The next iPhone will reportedly come with a brand new set of features aimed at toppling Apple’s main rivals.

iPhone 6 rumors point to a brand new A8 64-bit processor. A camera that will supposedly be equipped with image stabilization features for enhanced video. A sapphire display that could be virtually unbreakable. Two new high-resolution screen sizes. And a design that will supposedly be thinner than the iPhone 5s and closely resemble the iPod touch.

It’s those last two features that are of great interest to consumers. The display sizes would represent the largest iPhone screen sizes to date. If true, we’d likely see the iPhone grow in size from the 4-inch iPhone 5s. We’ve heard from many people who are excited, skeptical, and angry about the potential size change. They’re also curious.

Curious about how a larger iPhone 6 will stack up next to the iPhone 5s. Curious about how it might compare to top rivals like the Galaxy S5, HTC One M8 and Galaxy Note 3. And while we don’t have all of the answers, iPhone 6 leaks have supplied us with an arsenal of photos and videos that show what the iPhone 6 could look like next to some of these current smartphones.

iPhone 6 vs. iPhone 5s

Consumer are extremely interested in how the iPhone 6 will compare to the iPhone 5s, Apple’s current model. The iPhone 5s features a 4-inch Retina Display and a design the measures 7.6mm thin and weighs just 112 grams. The concern is that a larger iPhone 6 might dwarf the iPhone 5s.

While the iPhone 6 will almost certainly have to be larger to accommodate a larger display, rumors suggest that Apple will be doing all it can to keep the size difference to a minimum.

Rumors suggest that Apple could deliver an iPhone 6 that is up to 26% thinner than the iPhone 5s. A recent leak from Ukrainian website suggests Apple is aiming for a smartphone as thin as 6mm, but Ming-Chi Kuo of KGI Securities believes a 6.5 – 7mm thickness is easier for the company to achieve. Recent leaks agree with Kuo’s assessment and point to an iPhone 6 that could measure right around 7mm thin.

In a note shared by MacRumors, Kuo also says that he believes that the iPhone 6 will indeed come with a power button on the right and bezels that are narrower than those found on the iPhone 5s. In other words, this model lines up with current iPhone 6 rumors, though as we’ve pointed out, it’s possible that these mockups are off base.

These changes have been visualized in a number of ways. First, we’ve seen designers try their hand at illustrating the potential changes. deuxani, a user on the MacRumors forum, offered a collection of images that show just how a 4.7-inch iPhone 6 might compare to the iPhone 5s.

We’ve also seen supposed iPhone 6 dummy units compared to the iPhone 5s. The image below comes from Moscoat who took photos of the model next to the iPhone 5s. The photo shows just how thin the iPhone 6 might be compared to the iPhone 5s.

These iPhone 6 dummy units have also been shown off on video next to Apple’s current iPhone. The video below, from 9to5Mac, goes into great detail about the potential differences between the iPhone 5s and the iPhone 6 design.

We’ve also seen how a much larger iPhone 6 might compare to the iPhone 5s. Rumors suggest that Apple is working on a 5.5-inch version of its next iPhone. The photo below from Nowhereelse shows the potential size difference between the iPhone 5s and an iPhone sporting a 5.5-inch display. Like the 4.7-inch model, the 5.5-inch version is expected to be thin and rounded.

iPhone 6 vs. iPhone 5

Later this year, many iPhone 5 users will be coming off contract, looking for a new phone. Many we’ve spoken to are interested in Apple’s iPhone 6 and how it might compare to the size of the iPhone 5.

Well, given that the iPhone 5s borrowed from the iPhone 5’s design, the differences could mirror those seen above in the comparison to the iPhone 5s.

Those looking for a quick comparison can find one over on Sonny Dickson’s website. He compared the iPhone 6 dummy to all of Apple’s iPhones, including the iPhone 5. This iPhone 6 concept from Arthur Reis though offers a much more detailed look at how the new iPhone could compare to the 2012 model.

Reis’ concept is based on the iPhone 6 rumors that have emerged in recent months. It depicts a realistic looking 4.7-inch iPhone 6 next to the iPhone 5. Once again, we see how thin the iPhone 6 might be compared to the old design. We also get another glimpse at the other design changes, including the oval buttons.

iPhone 6 vs. Samsung Galaxy S5

The Samsung Galaxy S5 is Samsung’s latest flagship and it’s a device that almost certainly is going to be around when the iPhone 6 arrives. In fact, we’ve heard from many consumers who are debating between the two. We haven’t seen the real iPhone 6 compared to the 8.1mm thin Galaxy S5.

deuxani cooked up another illustration that shows us how a 4.7-inch iPhone 6 might compare to the 5.1-inch Android flagship. The iPhone 6 is noticeably smaller than the Galaxy S5, something that we’ve seen depicted in other photos and video.

Earlier this month, Macitynet posted photos that appear to show the iPhone 6 model next to the real Galaxy S5. The two photos show the potential size difference between two possible rivals.

9to5Mac also recently posted a video that shows the iPhone 6 dummy unit on film next ot the Verizon Galaxy S5. The comparison doesn’t offer anything new but it’s a much cleaner look at how the iPhone 6’s design could match up.

iPhone 6 vs. Samsung Galaxy Note 3

If Apple does release a 5.5-inch iPhone 6, the device will have to contend with the well known Samsung Galaxy Note series from Samsung. We expect the company to have a Galaxy Note 4 ready by the time the iPhone 6 arrives on shelves but the Galaxy Note 4 design hasn’t leaked out just yet.

Instead, consumers will have to settle with the image above that comes from Business Insider. While the image isn’t too detailed, it shows what the 4.7-inch and what the 5.5-inch iPhone 6 models could look like next to Samsung’s current Galaxy S and Galaxy Note lineup. The Galaxy Note 3, which comes with a 5.7-inch display, is larger than Apple’s 5.5-inch model.

iPhone 6 vs. HTC One M8

The 5-inch HTC One M8 is HTC’s current flagship smartphone and a device that should greet the iPhone 6 when it arrives later on this year. Like the iPhone 5s, the HTC One comes with a beautiful aluminum design that puts most Android smartphone designs to shame. It’s not as thin as the iPhone 5s, 9.35mm compared to 7.6mm, and that means that the iPhone 6 could have at least one distinct advantage.

Three photos tell the story. The first two come courtesy of Sonny Dickson and they show just how much bigger, and thicker, the 5-inch HTC One M8 could be.

The other comes courtesy of Moscoat and it gives us another look at the alleged size difference between the two flagships. The smartphone on the far left is the iPhone 5s.

iPhone 6 vs. LG G2 vs. Nexus 5

deuxani’s illustrations give us a look at how the iPhone 6, the 4.7-inch model, could compare to the 5-inch Nexus 5 and the 5.2-inch LG G2.

The LG G2 was recently replaced by the 5.5-inch LG G3, but price cuts should keep the LG G2 relevant until the iPhone 6 release. As for the Nexus 5, it will almost certainly be on shelves as a top Android rival.

Rumors suggest that Google has killed the rumored Nexus 6 and that its next big smartphone release, said to be Android Silver, may not come until next February.

iPhone 6 vs. Moto X

The 4.7-inch Moto X will be replaced this summer but there is a chance that it could stick around as a budget option for consumers. Here is how Motorola’s current 4.7-inch flagship might compare to the 4.7-inch iPhone 6.

The iPhone 6 seen here is much longer than the Moto X. It’s also longer than the LG G2 Mini, a smaller version of the 5.2-inch LG G2.
