According to Hair et al. not only parameters or observed items but also model complexity and number of constructs with communalities should be focused for sample size calculation. They mentioned that minimum sample size should be at least 500 if the model with large numbers of constructs (>7) and some with lower communalities and/or having fewer than three measured items.

Hi! G-power calculator can be used for sample size calculation. Thanks
Yes, I know that but use of any specific formula applicable for that will be appropriate or not dear Shamima Raihan Manzoor
You can estimate sample size for SEM based on model fit indices. The available methods and their web-applications are provided in the following book:

Thanks for sharing Dr. Mehmet Mehmetoglu and I wanted to know about the hardness or rigidity of use of that particular formula for all cases too.
