The global morphology and geometric parameters of 39 barred galaxies are investigated, by using isophote map and isodensity tracings obtained from detailed surface photometry with the Kiso V-band plates. The observed results are as follows: i) There is no strong indication that the ratio of bar length to disk size is correlated with Hubble type, except that the largest bars appear in the SBb galaxies. ii) The mean value of axial ratios of bars is 2.0+-0.4 and there is a trend that early type galaxies have smaller axial ratios than late type galaxies iii) About 15% of early type barred galaxies (Sb0-SBb) have triaxial bulges.
