@Column, @Length, @Size annotation in hibernate - used simultaneously

I try to understand which annotation for hibernate field have highest precedence. I use @Column, @Length and @Size for the same field and want to know which value will be taken to set column length in a database.

    @Column(name = "var", length = 5)
    @Length(max = 167)
    @Size(max = 64)
    private String var;

Using above code, column length in database is set to 167.

'Hibernate: create table test (id int4 not null, var varchar(167), primary key (id))'

    @Column(name = "var", length = 5)
    @Length(max = 168)
    @Size(max = 64)
    private String var;

But if I use this code I got column length equals to 64.

'Hibernate: create table test (id int4 not null, var varchar(64), primary key (id))'

Could you help me understand this? Do you know any reference which completely describe meaning of @Column, @Length and @Size annotation?
