Recently, the relevance of postcards,mailed by mail, has greatly increased. In the age of modern technology, high-speed Internet and affordable communication, almost no one uses mail. At least, if it comes to important matters. Now the mail is used as a kind of entertainment, allowing you to plunge into the past and rejoice in certain trifles - just these are postcards. You can buy a beautiful postcard or make it yourself, sign it and send it to a person close to you to please him. However, here the question arises: what is the size of a standard postcard? It would seem that there is no difference, but in fact it is very important. After all, the postcard should be placed in an envelope so that it can be safely sent by mail, without paying it as a special parcel. Accordingly, you need to know the size of the standard postcard in order to be able to forward it without problems. And also to ensure that the recipient, if he collects such parcels, could easily place your parcel in his collector's album.

Common standard

There is a specific generally accepted standard,which all manufacturers try to adhere to. The size of the standard postcard is designated as A6, that is, it has a smaller format than the ordinary A4 sheet. However, you hardly even know what the length and width of the paper A4 paper, although they have to deal with each person almost daily. So what is the size of the A6 format and, accordingly, the standard postcard? The size of the standard postcard is as follows: its width should be 105 millimeters, and the length - 148 millimeters. If your postcard is just this size, then you can rejoice - it fully meets international standards. However, so far only the specific size of the standard postcard has been considered - there are other indicators that also fall under the notion of "norms".

Range of sizes

Yes, the standardthe size of the postcard, but if you want to correspond to the norm, but do not want to make a card of this size - it's okay. The fact is that there is a certain range of sizes that are considered standard not less than the actual A6 format itself. So, the smallest permissible card size is 140 millimeters by 90 millimeters. However, most often people are interested in exactly the biggest size, since a small postcard will still fit in the envelope or in the pocket of the album. The maximum size is assumed to be 235 millimeters by 120 millimeters. If your postcard will have more in length or width - this will mean that it no longer applies to standard ones. Now you know what the standard postcard size is - but can you really use any length and width indicators in the above range? In fact, no, because the ratio of the sides of the postcard also has its own norms.

Aspect Ratio

The size of the standard postcard under the envelope was alreadyConsidered, however, one important aspect - the aspect ratio - was left out of view. The fact is that it is unlikely to greatly affect the convenience of delivery, since if both sides of the postcard comply with the standards, it will in any case calmly fit in the envelope. However, there are standards that have been recognized internationally, and in most cases it is considered that they must be observed so that the postcard is correct. The aspect ratio of it should be 1 to the square root of 2.

American features

Please note that the US has its ownFeatures that need to be considered if you are sending a postcard to this country. The fact is that the standards of Americans differ from international ones, and to a greater extent it affects the upper limit of the range. If the minimum ratio there is 127 millimeters to 89 millimeters, which is approximately similar to the lower limit of the international standard. But the upper limit is very different - the width of the postcard should not exceed 108 millimeters, and the height - only 153 millimeters, which, compared to 235 millimeters of the international size is quite small.
