Resolution Needed To Print An A4 Size Picture
To output an image properly it needs to have a certain minimum resolution. The number of pixels depends on the required output quality.
- At 300 ppi an A4-sized image needs to contain 2480 × 3508 pixels. This is the required resolution for quality offset printing that will be viewed from a short distance . For photo books, it is also the optimum resolution but a somewhat lower pixel count is fine for great-looking photographs.
- At 150 ppi the image needs to be 1240 × 1754 pixels. This is the minimum resolution for newspapers or posters viewed from a fairly short distance.
A digital camera with decent image quality and a resolution of 8 megapixels or more can be used to print high-quality A4 size pictures. A somewhat lower resolution is still fine. Ive had excellent results with my six-megapixel Nikon D70.
Whats The Difference A4 Paper Size Vs Letter
The difference is minimal, but important: A4 is a little taller, while Letter is a little wider.
Those of you from North America will be familiar with an entirely different set of paper formats to the rest of the world. While you go about your day, happily printing away on Letter paper, almost everyone else will be printing the same material on A4. As you can see in the picture above, these two paper sizes actually have different dimensions.
There is a good reason why most countries have accepted the ISO 216 series of paper sizes as a standard. Apparently first discovered by physics professor Georg Lichtenberg in 1786, the height-to-width ratio of these pages happens to have a rather nifty mathematical property. If you put two pages of one size together to create a new sheet of paper, they will have the same aspect ratio.
It just so happens that this is super handy when you want to scale a document up or down, for example by printing two-on-one page or fitting an A4 document to an A3 page. Because each sheet has the same aspect ratio, each item on the page retains its relative shapeSo your images dont suddenly appear stretched or squiffy and its easy to scale a document to fit the page.
Pro tip: If youre scaling an A-size page up to the next paper size, enlarge it by 141% to have it fit perfectly.
Simplified Enlargement And Reduction
Many copy machines have preset magnification factors for enlarging or reducing a copied document in order to print it on a different paper size. These presets typically take the form of buttons labelled A3A4 and so forth. This eliminates wasted margins and saves you the trouble of trying to guess the right magnification factor, which can lead to a heap of misspent paper. Below is a table of the magnification factors between the most common A sizes in case the copiers at your local library do not have such presets.

History Of The Iso Paper Formats
One of the oldest written records regarding the sqrt aspectratio for paper sizes is a letter that the physics professorGeorgChristoph Lichtenberg wrote 1786-10-25 to Johann Beckmann. In it, Lichtenbergexplains the practical and aesthetic advantages of the sqrt aspectratio, and of his discovery that paper with that aspect ratio wascommonly available at the time.
After introducing the meter measurement, the French governmentpublished 1798-11-03 the Loi sur letimbre , a law on the taxation of paper that definedseveral formats that already correspond exactly to the modern ISOpaper sizes: Grand registre = ISO A2, grand papier = ISO B3,moyen papier = ISO A3, petit papier = ISO B4, demi feuille = ISOB5, effets de commerce = ISO 1/2 B5.
The French format series never became widely known and was quicklyforgotten again. The A, B, and C series paper formats, which are basedon the exact same design principles, were completely independentlyreinvented over a hundred years after the Loi sur le timbre inGermany by Dr. Walter Porstmann. They were adopted as the Germanstandard DIN 476 in 1922 as areplacement for the vast variety of other paper formats that had beenused before, in order to make paper stocking and document reproductioncheaper and more efficient.

Untrimmed Ra And Sra Sizes
Although all the A Paper Sizes are well-definite, this does not solve all troubles. Printing is one such messy job. During mass printing, ink bleed is caused many times which causes the sides of the paper to be ruined and wetted with ink.
Thus, if something needs to print in A4 size the ink bleed and subsequent trimming of the inked part causes the paper size to reduce. To help with this, RA and SRA sizes are definite for commercial printing papers which still maintain the 2:1 aspect ratio. The A4 size in pixels is also available through our custom size table.
After o printing, these papers are then cut to one of the A Paper Sizes as needful. The maintaining of the aspect ratio helps in the trimming process too. We will try to write more in-depth about Printer paper size in our new guide. .

Of The Iso 216 Standard
A4 is part of a set or range of page sizes, called the ISO A or ISO 216 standard. This international standard is based on the German DIN 476 standard from 1922. A4 is actually often referred to as DIN A4. The Japanese have adopted the same range of paper sizes in their JIS P 0138-61 standard.
By folding an A4 in two along its shortest side, you create an A5 document. Two A4 pages next to each other in a spread equals the A3 paper size. This way a range of paper sizes is created from A0 to A10. The height/width ratio remains constant for all sizes: 1:1.41 or the square root of 2. The dimensions always get rounded to the nearest millimeter.

In the United States, standard paper sizes are decided by the American National Standards Institute, or ANSI. The norm in which all standardized paper dimensions can be found is called ANSI Y14.1.
In the rest of the world, the International Organization for Standardization, or ISO, presides over the regulation of paper sizing. ISO 216 is the internationally recognized norm for paper sizes.
Other paper standards do exist. And different countries have their own institutes responsible for developing norms. But the ANSI and ISO systems are the most common paper size standards around the world.

Printer Paper Dimensions In The United States
If you’re in the United States or Canada, the most common paper size you’ll encounter is letter-sized paper, which is 8.5 inches by 11 inches. Generally, if someone asks you to print a document for business, government or academic purposes, the paper size of 8.5 inches by 11 inches is the size they’ll expect to see, unless they say otherwise. It’s the most common paper size available for your printer at most office supply stores or stationery stores.
Documents are almost universally printed in portrait format, meaning that the longer dimension of the paper is treated as the vertical dimension. The alternative format, known as landscape format, generally is used only for printing specialized-use documents, such as charts, photos or other graphics.
Other common sizes you may encounter include legal size, which is 8.5 inches by 14 inches. This format is the same width as letter paper, but the paper is three inches longer on the long side. As the name suggests, it’s sometimes used as the standard paper size for certain types of legal documents.
Another paper size called ledger or tabloid, is 11 inches by 17 inches. When the paper is used in portrait orientation, it’s called tablet paper when it’s used in landscape orientation, it’s called ledger. As the names imply, it’s sometimes used for newsletters and for financial documents, as well as for other charts that won’t fit nicely on letter-sized paper or on legal-sized paper.
