Do you know **what is A Paper Sizes in Pixels**? We’ve stepped into the age of computers in the last decade. We use computers for all the purposes around us. Everything we do, right from reading news on mobile phones to scheduling deliveries and even manufacturing is through machines and computers. We’ve earlier talked about the importance of Standard Paper Sizes. But it is even more critical for us to understand how those paper sizes link up today in our world of computers.

**Why it is Important to Know A Paper Sizes in Pixels**

Architects work online and even draw online with special software today. But the building sites need physical blueprints to build. And these blueprints need to be in specific sizes as described by the **ISO 216**. Artists paint on Standard Size Papers and Canvas. But these need to be scanned and uploaded online for the world to view because not everyone can be physically present at a place to see a painting – and it is essential that everyone gets the opportunity to have the pleasure.

You see where we’re trying to get with this, right? In today’s online world, it is necessary to have a set of Standards for Paper Sizes even on digital documents because those documents keep changing forms between digital and physical as time demands. And it is essential that the digital sizes match or physical Standards for ease of handling.

**ISO 216 Statement About A Paper Sizes in Pixels**

ISO 216 has made this easier by describing Standard Paper Sizes in Pixels for those conversions to take place smoothly. And today, we’re talking about A Paper Sizes in Pixels. However, these Sizes cannot be exactly accurate because the pixels per inch (PPI) or dots per inch(DPI) vary from device to device.

And hence, ISO 216 has stated these dimensions by dividing into three categories namely – Low Resolutions, Medium Resolutions and High Resolutions and many further subcategories under these tags. We’ve clearly stated them below.

**A Paper Sizes in Pixels**

Choose the standard size from **Size** selector and pixels from **PPI/DDI **selector. The weight*height will be displayed in the right hand side box.

**1. Low Resolutions**

Low Resolutions compromise of resolutions that are below 300 PPI but above 72 PPI. These devices are generally old devices when technology wasn’t this far or smaller devices like low-resolution mobile screens or low-resolution projectors, etc.

Size | 72 PPI | 96 PPI | 150 PPI | 300 PPI |
---|---|---|---|---|

4A0 | 4768 x 6741 | 6357 x 8988 | 9933 x 14043 | 19866 x 28087 |

2A0 | 3370 x 4768 | 4494 x 6357 | 7022 x 9933 | 14043 x 19866 |

A0 | 2384 x 3370 | 3179 x 4494 | 4967 x 7022 | 9933 x 14043 |

A1 | 1684 x 2384 | 2245 x 3179 | 3508 x 4967 | 7016 x 9933 |

A2 | 1191 x 1684 | 1587 x 2245 | 2480 x 3508 | 4960 x 7016 |

A3 | 842 x 1191 | 1123 x 1587 | 1754 x 2480 | 3508 x 4960 |

A4 | 595 x 842 | 794 x 1123 | 1240 x 1754 | 2480 x 3508 |

A5 | 420 x 595 | 559 x 794 | 874 x 1240 | 1748 x 2480 |

A6 | 298 x 420 | 397 x 559 | 620 x 874 | 1240 x 1748 |

A7 | 210 x 298 | 280 x 397 | 437 x 620 | 874 x 1240 |

A8 | 147 x 210 | 197 x 280 | 307 x 437 | 614 x 874 |

A9 | 105 x 147 | 140 x 197 | 219 x 307 | 437 x 614 |

A10 | 74 x 105 | 98 x 140 | 154 x 219 | 307 x 437 |

Such devices hold a lower number of pixels per inch and hence for the same physical lengths and breadths of paper, they have a lesser number of pixels in dimensions compared to other higher PPIs.

** ISO has stated** the lengths and widths of A Series Paper Sizes in Pixels in portrait orientation for resolutions of 72 PPI, 96 PPI, 150 PPI and 300 PPI as these are the most common ones that devices in use have. The corresponding A Paper Sizes range as 4A0, 2A0, A0, A1, …, A10.

**72 PPI**

The largest size here is **4A0** with dimensions of **6741 pixels × 4768 pixels** while the smallest size is **A10** with dimensions of **105 pixels × 74 pixels**. The dimensions of the other A Paper Sizes in Pixels vary between these largest and smallest sizes.

**96 PPI**

The largest size in 96PPI is 4A0 with dimensions of **8988 pixels × 6357 pixels** while the smallest size is **A10** with dimensions of **140 pixels × 98 pixels**. The dimensions of other sizes vary between these.

**150 PPI**

The smallest size is A10 with dimensions of **219 pixels × 154 pixels** while the largest size here is **4A0** with dimensions of **14043 pixels × 9933 pixels**.

**300 PPI**

The largest size here is** 4A0** with dimensions of **28027 pixels × 19866 pixels** while the smallest size is **A10** with dimensions of **437 pixels × 307 pixels**. The other A Paper Sizes in Pixels vary between these sizes.

**2. Medium Resolutions**

Medium Resolutions are the resolutions that have Pixels Per Inch varying between 600 PPI and 1200 PPI. These devices are our modern-day computers with higher resolutions like 4K; even mobile devices with 4K screens that have higher PPIs.

Size | 600 PPI | 720 PPI | 1200 PPI |
---|---|---|---|

4A0 | 39732 x 56173 | 47679 x 67408 | 79464 x 112346 |

2A0 | 28087 x 39732 | 33704 x 47679 | 56173 x 79464 |

A0 | 19866 x 28087 | 23839 x 33704 | 39732 x 56173 |

A1 | 14043 x 19866 | 16838 x 23839 | 28066 x 39732 |

A7 | 1748 x 2480 | 2098 x 2976 | 3496 x 4961 |

A8 | 1228 x 1748 | 1474 x 2098 | 2456 x 3496 |

A9 | 874 x 1228 | 1049 x 1474 | 1748 x 2456 |

A10 | 614 x 874 | 737 x 1049 | 1229 x 1748 |

Such devices hold a lower number of pixels per inch compared to the High-Resolution ones but keep a more significant amount of pixels compared to the Low-Resolution ones and hence have an average number of pixels in dimensions regarding physical lengths and breadths of paper.

ISO has stated the lengths and breadths of A Paper Sizes in Pixels in portrait orientation for resolutions of 600 PPI; 720 PPI and 1200 PPI as these are the most common ones that devices with medium resolutions in use have. The corresponding physical A Paper Sizes are 4A0, 2A0, A0, A1, …, A10.

**600 PPI**

The largest size here is **4A0** with dimensions of **56173 pixels × 39732 pixels**; while the smallest size is **A10** with dimensions of **874 pixels × 614 pixels**. The other A Paper Sizes in Pixels vary between these stated sizes.

**720 PPI**

The smallest size is **A10** with dimensions of **1049 pixels × 737 pixels**; while the largest size here is **4A0** with dimensions of **67408 pixels × 47679 pixels**. The dimensions of other sizes vary between these largest and smallest sizes.

**1200 PPI**

**4A0** is the size with the most significant dimensions of **112346 pixels × 79464 pixels;** while the **A10** has the smallest dimensions of **1748 pixels × 1229 pixels**. The other A Paper Sizes in Pixels vary between these sizes.

**3. High Resolutions**

High Resolutions are the ones that have a large number of Pixels Per Inch i.e. a whopping 1440 PPI to 2880 PPI. Such sizes and resolutions can theoretically either be seen on a very minute or small screen; with a whopping 4K panel or on largest screens with 16K or higher panels.

Size | 1440 PPI | 2400 PPI | 2880 PPI |
---|---|---|---|

4A0 | 95357 x 134816 | 158928 x 224693 | 190715 x 269631 |

2A0 | 67408 x 95357 | 112346 x 158928 | 134816 x 190715 |

A0 | 47679 x 67408 | 79464 x 112346 | 95357 x 134816 |

A1 | 33676 x 47679 | 56131 x 79464 | 67351 x 95357 |

A2 | 23811 x 33676 | 39684 x 56131 | 47622 x 67351 |

A3 | 16838 x 23811 | 28063 x 39684 | 33676 x 47622 |

A4 | 11906 x 16838 | 19843 x 28063 | 23811 x 33676 |

A7 | 4195 x 5953 | 6991 x 9922 | 8391 x 11906 |

A8 | 2948 x 4195 | 4913 x 6991 | 5896 x 8391 |

A9 | 2098 x 2948 | 3508 x 4913 | 4195 x 5896 |

A10 | 1474 x 2098 | 2480 x 3508 | 2948 x 4195 |

But, in fact, such PPIs are hardly ever achieved on screens. These PPIs are only available in high-resolution scanners; printers which are used to print either very minute details like chips, etc.; or large flexes which need things to be perfect and of great quality.

They host a large number of pixels for corresponding physical lengths and breadths as they have such high pixel densities. ISO has stated the lengths and breadths of A Paper Sizes in Pixels in portrait orientation for resolutions of 1440 PPI, 2400 PPI; 2880 PPI as these are the most common ones that are in use. The corresponding physical A Paper Sizes range as 4A0, 2A0, A0, A1, …, A10.

**1440 PPI**

**4A0** is the size with the largest dimensions of **134816 pixels × 95357 pixels** while the smallest size **A10** has dimensions of **2098 pixels × 1474 pixels**. The other A Paper Sizes in Pixels vary between these stated sizes.

**2400 PPI**

The smallest size is **A10** with dimensions of **3508 pixels × 2480 pixels** while the largest size here; is **4A0** with dimensions of **224693 pixels × 158928 pixels**.

**2880 PPI**

Here, **4A0** has the largest ever possible dimensions of **269631 pixels × 190715 pixels**; even the smallest size **A10** has dimensions **4195 pixels × 2948 pixels** which are bigger than dimensions of A10s in all other PPIs. The dimensions of other A Paper Sizes in Pixels range in between these maximum and minimum dimensions.

## Conclusion

Even when being reborn into A Paper Sizes in Pixels; these A Papers maintain their fundamental property of the √2:1 aspect ratio as per the ISO 216 Guidelines.

Everyone is going online. Right from vegetable vendors to even authors. In this online world, it is essential that we don’t forget the past knowledge. The books that were written ages ago, we preserve them, but honestly speaking, we all know those pages won’t survive another five centuries.

They would get rustled and decomposed – and the knowledge, lost. It is essential that we convert those books and upload them to the computers or the cloud so that they are preserved, forever.
