# Size

- `Size(string $minSize)`
- `Size(string $minSize, string $maxSize)`
- `Size(null, string $maxSize)`

Validates whether the input is a file that is of a certain size or not.

```php
v::size('1KB')->validate($filename); // Must have at least 1KB size
v::size('1MB', '2MB')->validate($filename); // Must have the size between 1MB and 2MB
v::size(null, '1GB')->validate($filename); // Must not be greater than 1GB
```

- B
- KB
- MB
- GB
- TB
- PB
- EB

This validator will consider `SplFileInfo` instances, like:

```php
v::size('1.5mb')->validate(new SplFileInfo($filename)); // Will return true or false
```
