Calculating the effect size for
Calculating the effect size for the chi-square test of independence in SPSS is essential to quantify the difference between the observed and expected counts. To measure the association within the chi-square test of independence, Cohen's ω (sometimes: just w) is suitable.

Cohen (1988) provides the proper formula on p. 223. You will take the square root of the chi-square value divided by the number of observations.
A classification should first consider prior evidence/similar studies. If none exist, use reasearch field specific thresholds. As a fallback, you can refer to Cohen, J. (1992), A Power Primer, p. 157. The thresholds are 0.1, 0.3. and 0.5 for small, medium and large effects.
