Counterclockwise: the quest for the all screen front in numbers

A couple of years ago we looked at the ever shrinking bezels and the rising screen to body ratio. While 2016 wasn’t that long ago, things have changed considerably since.

The last article stopped at 2016’s Xiaomi Mi Mix. Fitting that 6.4” screen in a body that small was quite a feat, but it required some contortion – putting the selfie camera on the bottom (a trend started by Sharp’s Aquos and the Nokia N9 phones).

This didn’t catch on, however, and instead we got the likes of the Essential PH-1 – the champ for 2017 and one of the first notched phones. The Sharp Aquos S2 was released just days earlier, both came out before the iPhone X.

Year	Average	Best	Best phone
2007	27.70%	52.00%	Apple iPhone
2008	30.18%	57.39%	HTC Touch HD
2009	36.90%	65.19%	HTC HD2
2010	41.48%	65.46%	HTC Evo 4G
2011	46.91%	67.63%	HTC Titan
2012	54.80%	72.39%	Panasonic Eluga Power
2013	60.18%	78.45%	Alcatel Hero
2014	64.94%	78.52%	Sharp Aquos Crystal
2015	66.56%	78.38%	Huawei Mate 8
2016	69.57%	84.02%	Xiaomi Mi Mix
2017	70.95%	84.86%	Essential PH-1
2018	78.72%	88.53%	Lenovo Z5 Pro
2019	83.06%	89.37%	Samsung Galaxy S10 5G

The notch – the way that Sharp and Essential did it, rather than how Apple did it – doesn’t take up much room. And it even became moderately aesthetic once makers adopted the “teardrop” design.

Notches were quickly displaced by “full-screen” designs in the screen to body ratio rat race. The Mi Mix 3 was an early example of the slider approach – a sliding mechanism is used to put the selfie cam behind the screen (which unlike the fingerprint reader can’t go behind the screen and stay there).

Less than a month after, Lenovo Z5 Pro came out and really pushed the StB ratio high. The original Mi Mix, the Essential and the Mi Mix 3 all hover around the 85% mark, Lenovo managed better than 88%.

Sliders are still a niche and

may be going extinct now that various pop-ups have appeared – large and small pop-ups (e.g. Oppo Find X and OnePlus 7 Pro), shark fins (Oppo Reno 10x zoom) and others (Samsung Galaxy A80 and Asus Zenfone 6).

However, none of these can claim to be the champ – the Samsung Galaxy S10 5G claims the top spot with a simple but popular development of the notch. The so-called “punch hole cameras” really not that different from notches, other than wasting space in the corner rather than the center.

The 5G has the biggest “punch hole” of all four S10 models (there’s a camera and a ToF module in there), but it’s the champ for a simple reason – it’s all in the name, screen to body ratio.

A 1mm bezel on a 5” screen looks average, on a 6+ screen it starts to look razor thin. And it’s not just looks either, it’s how the math works out too. In fact, all the top phones (in terms of StB ratio) have larger than average displays. The table below proves it.

Note: we’ve excluded phones of extremely low popularity to avoid outliers that you'll never encounter skewing the data.

If all goes to plan next time we try to write an article about screen to body ratios, we’ll have to go above 100% - as foldable phones will certainly be the next big thing in that area.
