Laravel schema builder INT(11) on integer() and INT(10) on unsignedInteger()

Question

Why does Laravel create the integer column as INT(11) and unsigned integer column as INT(10)?

$table->integer('integer'); // INT(11)
$table->unsignedInteger('unsignedInteger'); // INT(10) unsigned
$table->integer('integer_then_unsigned')->unsigned(); // INT(10) unsigned

Since the unsigned integers maximum value can be almost twice as large, shouldn't it rather be the other way around?

Answer 1

Because of the minus sign when integer can be signed.

Unsigned integers will have 10 digits, and its display length is therefore - 10.

Signed integers will require a space for the minus sign, if it's negative. Therefore, on top of 10 digits, you need another one for the sign.

Answer 2

It is because the minus sign in case your column is signed, which allows the field to have negative integers. You can have up to 10 digits when your field is unsigned.
