Web applications are popular due to the ubiquity of the web browser s a client, sometimes called a thin client. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity.

Accurate estimates of development effort play an important role in the successful management of larger Web development projects. By applying measurement principles to measure qualities of the applications and their development processes, feedback can be obtained to help understand, control and improve products and processes.

The objective of this paper is to present a metrics for Web design based on a set of metrics, which were collected using a case study evaluation (CSE). The paper is organised into two parts. Part I describes the CSE for Proprietary (ASP) and Non-proprietary (PHP) server programs for which the web metrics used were collected. These metrics were organised into four categories: structure metrics, complexity metrics, reuse metrics and size metrics. Part II presents the Problem and solution oriented metrics (FP and LOC) for the above given metrics.
