You can install a custom css plugin (do a search for the plugin Simple Custom CSS). Once installed, it should show up in your Appearance menu. Using the Custom CSS plugin:
Copy & Paste the styles below. Replace the width with the width that you would like to use. !important ensures that your custom style will have priority over the default style.
Start Copy & Paste Below this line. Replace the width value with your value.
.postimage,
.postimage img {
width: 150px!important;
}
.griditemleft {
width: 150px!important;
}
End Copy & Paste Above this line
Thanks. It works perfect:)

Ok. I got another questions:
If I want to archive pages/category pages also have this format, what should I change in css.
I try to experiment with numbers:
.postimage,
.postimage img {
width: 270px!important;
height: 200px!important;
}
.griditemleft {
width: 270px!important;
padding: 5px!important;
}
but how can I center my images?
Sorry for the delay. Do you want to center the entire grid? I will be updating the code this week.
