No.
The ratio (length : width) of the sides of a sheet of the A series of papers (of which A4 is one) is √2 : 1 ≈ 1.414 : 1
Alternatively, the ratio can be expressed as 1 : 1/√2 ≈ 1 : 0.707
A golden rectangle has sides in the ratio (length : width) of φ : 1 = (√5 + 1)/2 : 1 ≈ 1.618 : 1
Alternatively, the ratio can be expressed as 1 : 1/φ = 1 : 2/(√5 + 1) = 1 : (√5 - 1)/2 ≈ 1 : 0.618
flowers, building, an A4 paper etc. mostly in nature.
Half of A4 is A5.
An A4 sheet measures 210 x 297 mm. An A4 sheet of paper is the more common business and school size paper in most of the world, including Europe, whereas the 8½ x 11 inch sheet of paper is the more common business size in the USA. A4 is a little taller and narrower than a US 8½ by 11 inch sheet.
Two - A sheet of A4 paper is exactly half the size of a sheet of A3.

Sheets of paper in the A and B series (A4 being the most common).
No. The golden ratio is approximately 1.618. The A4 paper uses something known as the Lichtenberg ratio 1:sqrt(2). If you cut a piece of A4 paper in half, the sides of the smaller sheets would maintain the same ratio. That's why A4 is exactly half the size of an A3 sheet, and A3 is exactly half of an A2 sheet, and so on.
The weight of an A4 sheet of paper can vary depending on the thickness and material of the paper. Typically, an A4 sheet of regular printer paper weighs around 5 grams.
Any sheet of paper in the An series - A4 being the most common size for printers and copiers.
If you use A4 paper (rather than letter size) you are using it. every day.
No, it does not. Take a sheet of A4 paper and fold it across the diagonal, and you will see that the two halfs do not line up.
Half of A4 is A5.
A standard vanguard sheet measures 22 inches by 17 inches, which is larger than an A4 sheet of paper. You would be able to fit less than one A4 sheet on a vanguard sheet.
An A4 sheet measures 210 x 297 mm. An A4 sheet of paper is the more common business and school size paper in most of the world, including Europe, whereas the 8½ x 11 inch sheet of paper is the more common business size in the USA. A4 is a little taller and narrower than a US 8½ by 11 inch sheet.
